None work, the firmware was installed by the Canaan team via teamviewer. I do not recall which version they installed but I will check when I go back to the farm later today.
A thought - did Canaan supply the USB-A to micro USB cable? If not, a very common issue with supplying your own is that many such cables are ONLY for charging and do not support data transfer because all 4 wires in them are used for power. Try using a known good data/charging cable.
