Recently, we got the opportunity to take a look at an interesting video capture device from a company called Pengo. While we had never heard of this company before, the promises of 4K 60Hz video capture at the price of $150 were too compelling to pass up.
Also, the Pengo 4K is a UVC capture device, which means that it uses the standard Microsoft video drivers, meaning it will work with any application capable of seeing camera input from a webcam and requires no additional software/drivers. Pengo also claims support for Mac OS and Linux with this device, although you would have to find software that knows how to deal with UVC devices.
From a design perspective, the Pengo 4K is quite simple. The device itself is made from aluminum and about the size of a deck of playing cards.
In addition to video capture, you can also use the Pengo as an audio input/output device through the audio connectors on the front.
Taking a look at the back of the Pengo, we can see my one major gripe with the device. Instead of using a proper port like MicroUSB or USB-C, the device ships with a Type-A to Type-A cable, which is actually against the USB specifications and will make finding a replacement cable, or a cable longer than the included cable (about 1 foot) difficult.
In this case, we used OBS to record footage from the Xbox One X using the Pengo 4K. Here, we can see that the Xbox is, in fact, capable of outputting full 4K 60Hz content to this capture card.
However, if you do some further investigation, we found that while the Pengo capture device ingests 4K footage, it is only actually capable of recording at 1080p 60Hz, meaning that it internally downsamples the footage.
While this still makes sense to some degree, allowing you to keep your console or PC in 4K for your local display while gaming, it's disappointing to see the capture functionality limited to 1080p. To be fair, the recording limitations of the Pengo are hidden on the specifications page, but overall it seems disingenuous to market this device heavily as "4K".
For anyone looking for an inexpensive, easy to use capture device, I would still recommend taking a look at the Pengo 4K HDMI Grabber. However, if you are looking for true 4K capture, this is not the device for you.

Synopsys has just published a video on YouTube where they connect two bonded lanes over a standard Type-C cable. This was accomplished with a host USB 3.2 controller embodied by an FPGA board. The device controller is the same hardware that was configured to be seen by the pair as a USB device.
In case you're wondering, the demo happens at around 1:48. Blink and it's over.
From a practical standpoint, USB 3.2 is still some time away, and a factor of 2 speed-up is not too large considering the amount of bandwidth that USB 3.1 already provides. That said, more bandwidth is always better, especially when you’re running in industrial or other professional workloads, and especially in places where Thunderbolt has marketshare.

The USB Implementers Forum recently published and made official the specifications for the USB 3.2 standard first introduced in near-final form by the USB 3.0 Promoters Group back in July. The USB 3.2 standard specifies the physical and logical techniques for transferring data over physical USB cables (which are now all specified under their own standards decoupled from the USB 3.2 data transfer specifications) at up to 20 Gbps (~2 GB/s) using two 10 Gbps channels and the same signaling and 128b/132b encoding used by USB 3.1.
Like Thunderbolt, USB 3.2 takes advantage of multiple lanes to achieve the total bandwidth rather than trying to clock and run a single channel at twice the speed which is incredibly complex. In the case of USB 3.2, the specification defines two channels that can run 2 x 5 Gbps or 2 x 10 Gbps depending on the cable used with USB 3.1 Gen 1 (5 Gbps) or USB 3.1 Gen 2 (10 Gbps) cables respectively. In fact, users will be able to re-use their existing USB Type C cables to connect USB 3.2 hosts to USB 3.2 devices so long as they are up to spec. The USB-IF is able to achieve this by using the extra wire pairs in the Type C cables to enable the two lane operation. (5 Gbs cables would be upgraded to 10 Gbps speeds and 10 Gbps cables would be upgraded to 20 Gbps speeds when used with 3.2 hardware at both ends.)
The specification is expected to be finalized by the end of the year with USB 3.2 controllers and other hardware to begin production and roll outs in 2018. Devices supporting the faster USB 3.2 standard are expected as soon as 2019. Desktop users should get access first in the form of PCI-E add-on cards with new USB 3.2 controllers from third parties with native CPU and chipset support from AMD and Intel following in a generation or two (processor generation that is). Laptop and mobile users will have to wait until at least 2019 if not later for the faster standard to come standard.
It is interesting that they have decoupled the USB data transfer standard from the physical cable standards. It seems that USB Type C cables are the star of the show, but that cables like Type A and Micro cables are not going away and could be used with USB 3.2 with the caveat that you would need to buy new USB 3.2 cables which should be backwards compatible with older USB standards but current cables (SuperSpeed Type C cables being the exception) aren't forwards compatible--they might work but will support the higher speeds. At least that is my understanding of it. I am curious if Type C will be more prevalent with USB 3.2 or if we will still see motherboards with a single USB Type C nestled among many more Type A ports. I suppose the number of Type C vs Type A ports will all depend on how many new devices adopt Type C as the USB 3.2 physical interface of choice though, something we will just have to wait and see on! It is nice to see some competition for Thunderbolt though even at 20 Gbps USB 3.2 still lags behind the 40 Gbps of Thunderbolt 3 (20 Gbps with passive copper cables) which Intel is allegedly planning to make royalty free next year. USB 3.2 also has more overhead and is less ideal for things like external graphics. On the other hand, it may just be the cheap enough and fast enough connector that will get the design wins while Thunderbolt continues to be more of a prosumer and professional interface for the higher end and expensive motherboards, PCs, and end devices.
If you are interested in the new 20 Gbps USB 3.2 specifications, the USB-IF has provided a 103 MB zip file with several documents including a 548 page PDF of the new standard and a redline comparison between it and USB 3.1 among other related documents for developers.

Kicking off the storage announcements at CES 2017, Kingston announced a 2TB thumb drive:
Ok, well it's a bit big for a thumb drive, but it is definitely a high capacity portable SSD with a narrower profile (width wise) than a Samsung T3, and is meant to be plugged directly into a USB port. Thickness may be an issue for some applications, but I assume they would include a short extension for those trying to plug into tighter spaces like at the rear of a PC case. The release was light on details, particularly performance, though I'd expect these to be able to do a few hundred MB/s on sequentials at a minimum. More should come out about this and other Kingston products later in the week.
*edit* Here's a couple of pics I snagged at one of the events here:

Introduction, Specifications, and Packaging
Western Digital launched their My Passport Wireless nearly two years ago. It was a nifty device that could back up or offload SD cards without the need for a laptop, making it ideal for photographers in the field. I came away from that review wondering just how much more you could pack into a device like that, and today I get to find out:
Not to be confused with the My Passport Pro (a TB-connected portable RAID storage device), the My Passport Wireless Pro is meant for on-the-go photographers who seek to back up their media while in the field but also lighten their backpacks. The concept is simple - have a small device capable of offloading (or backing up) SD cards without having to lug along your laptop and a portable hard drive to do so. Add in a wireless hotspot with WAN pass-through along with mobile apps to access the media and you can almost get away without bringing a laptop at all. Oh, and did I mention this one can also import photos and videos from your smartphone while charging it via USB?
- Capacity: 2TB and 3TB
- Battery: 6,400 mAH / 24WH
- UHS-I SD Card Reader
- USB 3.0 (upstream) port for data and charging
- USB 2.0 (downstream) port for importing and charging smartphones
- 802.11AC + N dual band (2.4 / 5 GHz) WiFi
- 2.4A Travel Charge Adapter (included)
- Plex Media Server capable
- Available 'My Cloud' mobile apps
No surprises here. 2.4W power adapter is included this time around, which is a nice touch.

Qualcomm has announced Quick Charge 3.0, the latest iteration of their fast battery charging technology. The new version is said to not only further improve battery charging times, but also better maintain battery health and reduce temperatures.
One of the biggest issues with fast battery charging is the premature failure of the battery cells; something my first Nexus 6 (which was replaced due to a bad battery) can attest to. The new 3.0 standard adds "Battery Saver Technology" (BST) which constantly varies the current delivery rate based on what the battery can safely accept, thus preventing damage to the cells. This new version of Quick Charge also claims to offer lower temps while charging, which could be partly the result of this variable current delivery.
The other change comes from "Intelligent Negotiation for Optimum Voltage" (INOV), which can vary the voltage delivery anywhere from 3.6V to 20V in 200mV increments depending on the device's negotiated connection. INOV will allow Quick Charge 3.0 to charge a full 2x faster than the original Quick Charge 1.0 (it's 1.5x faster than QC 2.0), and 4x over standard USB charging as it provides up to 60W to compatible devices.
This new Quick Charge 3.0 technology will be available soon with devices featuring upcoming Qualcomm SoCs such as the Snapdragon 820.

Bask in the glory that is this hacked together 33 port USB charger, created in the Netherlands as a workaround to connet the charges to the three rounded prongs used in Schuko sockets common in Europe. This would of course work with NEMA plugs, just line the welding rods up appropriately and connect your USB chargers up to it. Keep in mind that they use 220-240V whereas we use 110-120V so your total workable amount of plugs will vary. If you are considering building your own version of this massive USB charger, you might want to seriously consider installing some sort of circuit breaker in addition to the non-conductive cowling unless you are a fan of dead devices and house fires. Check Hack a Day for other projects from this event and others around the world.
"The Hack42 hackerspace in Arnhem, The Netherlands had collected a large number of TP-Link 5V USB chargers – but all of them had the North American NEMA plug (flat, 2 pin) which wouldn’t fit the Schuko sockets prevalent in The Netherlands. [Simon “MacSimski” Claessen] decided to whip out his giant soldering iron and use it to solder two long pieces of welding filler metal rods to 33 of the chargers, effectively wiring them up in parallel."

Logitech Focuses in on Gaming
Logitech has been around seemingly forever. The Swiss based company is ubiquitous in the peripherals market, providing products ranging from keyboards and mice, to speakers and headsets. There is not much that the company does not offer when it comes to PC peripherals. Their 3 button mice back in the day were considered cutting edge that also happened to be semi-programmable. Since that time we have seen them go from ball mice, to optical mice, to the latest laser based products that offer a tremendous amount of precision.
Gaming has become one of the bigger movers for Logitech, and they have revamped their entire lineup as well as added a few new products to hopefully cash in on the popularity of modern gaming. To further address this market Logitech has designed and marketed a new batch of gaming headsets. These promise to be moderately priced, but high quality products that bear the Logitech name. We go from the very basic up to the top 7.1 wireless products. Originally these covered a pretty significant price range, but lately the discounts have been extremely deep. The lowest end gaming headset is at $40US while the 7.1 wireless model comes in around $90 US.
I am looking at two models today that span the lowest end to the 2nd highest. The first headset is the G230 analog set. The second is the G35 wired 7.1 USB with Dolby Headphone technology. I have never been a fan of wireless headphones, but the G35 should be a fairly good approximation of the performance of that part.
My goal is to look at these two wired units and see what Logitech can offer at these two very affordable price points.
Introduction, Specifications, and Packaging
Lexar is Micron’s brand covering SD Cards, microSD Cards, USB flash drives, and card readers. Their card readers are known for being able to push high in the various speed grades, typically allowing transfers (for capable SD cards) much faster than what a typical built-in laptop or PC SD card reader is capable of. Today we will take a look at the Lexar ‘Professional Workflow’ line of flash memory connectivity options from Lexar.
This is essentially a four-bay hub device that can accept various card readers or other types of devices (a USB flash storage device as opposed to just a reader, for example). The available readers range from SD to CF to Professional Grade CFast cards capable of over 500 MB/sec.
We will be looking at the following items today:
- Professional Workflow HR2
- Four-bay Thunderbolt™ 2/USB 3.0 reader and storage drive hub
- Professional Workflow UR1
- Three-slot microSDHC™/microSDXC™ UHS-I USB 3.0 reader
- Professional Workflow SR1
- SDHC™/SDXC™ UHS-I USB 3.0 reader
- Professional Workflow CFR1
- CompactFlash® USB 3.0 reader
- Professional Workflow DD256
- 256GB USB 3.0 Storage Drive
Note that since we were sampled these items, Lexar has begun shipping a newer version of the SR1. The SR2 is a SDHC™/SDXC™ UHS-II USB 3.0 reader. Since we had no UHS-II SD cards available to test, this difference would not impact any of our testing speed results. There is also an HR1 model which has only USB 3.0 support and no Thunderbolt, coming in at a significantly lower cost when compared with the HR2 (more on that later).
One hub to rule them all!
Inateck sent along a small group of connectivity devices for us to evaluate. One such item was their HB7003 7 port USB 3.0 hub:
This is a fairly standard powered USB hub with one exception - high speed charging. Thanks to an included 36W power adapter and support for Battery Charging Specification 1.2, the HB7003 can charge devices at up to 1.5 Amps at 5 Volts. This is not to be confused with 'Quick Charging', which uses a newer specification and more unique hardware.
- L/W/H: 6.06" x 1.97" x 0.83"
- Ports: 7
- Speed: USB 3.0 5Gbps (backwards compatible with USB 2.0 and 1.1)
- Windows Vista / OSX 10.8.4 and newer supported without drivers
Densely packed brown box. Exactly how such a product should be packaged.
Power adapter (~6 foot cord), ~4.5 foot USB 3.0 cord, instruction manual, and the hub itself.
Some quick charging tests revealed that the HB7003 had no issue exceeding 1.0 Amp charging rates, but fell slightly short of a full 1.5A charge rate due to the output voltage falling a little below the full 5V. Some voltage droop is common with this sort of device, but it did have some effect. In one example, an iPad Air drew 1.3A (13% short of a full 1.5A). Not a bad charging rate considering, but if you are expecting a fast charge of something like an iPad, its dedicated 2.1A charger is obviously the better way to go.
Performance and Usability:
As you can see above, even though the port layout is on a horizontal plane, Inateck has spaced the ports enough that most devices should be able to sit side by side. Some wider devices may take up an extra port, but with seven to work with, the majority of users should have enough available ports even if one or two devices overlap an adjacent port. In the above configuration, we had no issue saturating the throughput to each connected device. I also stepped up to a Samsung USB T1 which also negotiated at the expected USB 3.0 speeds.
Pricing and Availability
- $34.99 (Amazon)
Inateck is selling it these direct from their Amazon store (link above).
- Clean design 7-port USB 3.0 hub.
- Port spacing sufficient for most devices without interference.
- 1.5A per port charging.
- Low cost.
- 'Wall wart' power adapter may block additional power strip outlets.
At just $35, the Inateck HB7003 is a good quality 7-port USB 3.0 hub. All ports can charge devices at up to 1.5A while connecting them to the host at data rates up to 5 Gbps. The only gripe I had was that the hub was a bit on the light weight side and as a result it easily slid around on the desk when the attached cords were disturbed, but some travelers might see light weight as a bonus. Overall this is a simple, no frills USB 3.0 hub that gets the job done nicely.
