I reviewed a different but very similar Cable Matters cable a couple of weeks ago : Cable Matters® USB 3.1 Type C (USB-C) to Type A (USB-A) Cable in White 3.3 Feet
I found that cable to be not correctly following the USB Type-C specification. In the weeks since my review, Cable Matters got in touch with me and let me know that they were aware of the issue and they were in the process of fixing it. They were kind enough to send me early engineering samples.
Today I am reviewing Cable Matters® USB 3.1 Type C (USB-C) to Type A (USB-A) Cable in Black 3.3 Feet, which I had on order from Amazon.
Let's check spec compliance :
I'm using my trusty Chromebook Pixel 2015 with the Chromium Twinkie USB-PD Sniffer, available on Amazon from Plugable : Plugable USB 3.1 Type-C (USB-C) Power Delivery Sniffer
For my first test, I've got the Cable Matters cable plugged into a Dell 10W charger : Dell 10W Adapter Spare Wall Charger for Venue 8 Pro/8/7 (XDN34)
The Type-C end is plugged into Twinkie, acting as a pass through to Chromebook Pixel 2015. Picture attached!
localhost ~ # ectool --name=cros_pd usbpdpower
Port 0: SNK Charger DCP 4901mV / 2000mA, max 5000mV / 2000mA / 10000mW
Port 1: SRC
So far so good. Pixel identifies the charger as a DCP (dedicated charging port) type adapter, and has negotiated 2A 10W of charging.
Let's see what Twinkie says :
CC1_PD = 437
CC2_PD = 16
The ADC command reads the current voltage values from the CC pins. As you can see here, CC1_PD pin has a value of 437mV. Referring to the USB Type-C Specification Table 4-25 Voltage on Sink CC pins, this voltage falls right in the middle of the range allowed for vRd-USB, meaning that yes, this cable has the correct 56kΩ pullup resistor!
One more command :
> tw vbus
VBUS = 4960 mV ; -2033 mA
The tw vbus command uses twinkie's current and voltage meter ability. As you can see, the laptop is pulling just around 2A of current at 4.960V from the Dell adapter.
For more subjective evaluation of the cable : the cable's Type-C plug is quite good. It has good insertion and detach feel in both directions. The cable itself thicker and sturdier than CableMatters’s 2.0 cables, in order to accomodate the SuperSpeed lines.
Speaking of which, this is a USB 3.1 Gen 1 cable, meaning it contains all of the wires necessary to support USB 3.1 Gen 1 (5gbps). Practically speaking, this is most important for MacBook users who want to use Target Disk Mode, which requires a USB 3.1 Gen 1 cable.
In conclusion : This is a fine USB Type-C cable from Cable Matters. I was very impressed by their customer service and the speed at which they fixed the original defect in their product line. The cable itself is a great safe way to charge and data sync your new USB Type-C devices such as Nexus 6P/5X or Pixel devices. It is also future proof for USB Type-C devices to come!
It seems to me like Cable Matters is still selling some of their defective stock to unsuspecting buyers, so I would caution you to wait until the stock is completely of the revised cables.
See my attached screen-shot showing what the CheckR app shows (a red "X" USB icon). I have tested using this cable on my Nexus 6P with both my USB 3 and USB 2 ports on my desktop computer.
Make sure you get a compliant cable or you can damage devices you use with Type A to Type C cables. Why USB 3.1 didn't just use Type C to Type C on everything I will never know but it makes an absolute MESS just for the sake of having the port be backwards compatible. Why the heck am I going to use the 3.1 port for 3.0 or 2.0 stuff? That's what the other 6 ports on the motherboard are for. USB standards say these cables aren't actually allowed because of the potential dangerous connections that can be made, and they're right! How are us desktop users with only 3.1 Type A ports supposed to hook up Type C stuff to our computers if these cables aren't allowed/safe? USB screwed it up with 3.1.
This cable is USB 3.1 Gen 1, which means it's just USB 3.0, so no point in plugging it into a USB 3.1 port, anyway.
I left my phone connected for to the PC for about an hour today and went to check on a phone notification with the pull-down and found a 5-item menu for the USB connection. The third choice was "Transfer Files". I really wish I'd discovered this sooner. I've had this cable for a month, but now, all is well.
Update. Cable matters sent a replacement cable and it tests fine. Cable is thick and looks like quality
When I e-mailed Cable Matters (email@example.com), they responded right away and agreed to replace the noncompliant cables that I received. The replacement cables that I received from Cable Matters passed the Checkr test without any issue.
This is a very nice cable. The connectors feel strong and the cable feels solid. And Cable Matters customer service is great; they even responded to my e-mails on Thanksgiving day!
Edit: The problem was cleared up. Apparently the CheckR app isn't working properly. I would trust that this cable is compliant (As Benson Leung gave his approval.)
