For my first test, I've got the VCE cable plugged into an Apple proprietary Type-A charger, 12W version.
The Type-C end is plugged into Twinkie, acting as a pass through to Chromebook Pixel 2015. Picture attached! localhost ~ # ectool --dev 1 usbpdpower Port 0: SNK Charger Proprietary 4612mV / 2400mA, max 5000mV / 2400mA / 12000mW Port 1: SRC
So far so good. Pixel identifies the charger as an Apple proprietary type adapter, and has negotiated 2.4A of charging.
Let's see what Twinkie says : > tw cc CC1 = 11 mV ; CC2 = 431 mV
The "tw cc" command reads the current voltage values from the CC pins. As you can see here, CC2 pin has a value of 431mV. 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 56k' pullup resistor!
For a High Speed USB 2.0 data test, I’ve hooked my Nexus 5X to my Chromebook Pixel via the VCE cable to test large file transfer via MTP. It just works, no problem!
For a USB 3.1 SuperSpeed data test, I've hooked up my Pixel C to a Windows 10 laptop using the VCE cable, and verified that it indeed enumerates at SuperSpeed using the USBView.exe debug app, and that large file transfers are stable. This is a great cable to have for MacBook users especially who want to use Target Disk Mode, which requires a SuperSpeed capable USB cable.
For more subjective evaluation of the cable : VCE’s cable has aluminum shells on both ends, which meshes well with the all aluminum new MacBook, Chromebook Pixel 2015 and Nexus 6P. The length of the cable itself is black PVC. The C plug is a stamped variety, meaning it has a seam on one side of it, unlike other higher quality cables from Apple or Google which have deep-draw extruded plugs which are stronger.
In conclusion : This is a fine USB Type-C cable from VCE. The cable 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 future proof for fast charging USB Type-C devices to come, as well as future proof for USB 3.1 SuperSpeed devices!
