Public bug reported:
I'm running a WeTab with ubuntu and the ch7036 chip is not supported.
There is a driver for the chromebook (called chrontel), but that driver is more
or less a hacked daemon that sends some data to the chip and gives me the
following error message:
Found device ID 0x56
Found revision ID 0x81
Mode 1366x786 (44)
1366y786, dot clock 69300000 -Hsync -Vsync
H: start 1414, end 1446, skew 0, total 1456
V: start 771, end 777, total 793
State: 0
Firmware size = 3295 bytes.
State: 2
State: 3
Timeout waiting for MCU to return EDID
CH7036 MCU ver 1.41, Device 56 rev 1 capability 0x1
EDID timed out: Ignore HPD because EDID failed just after firmware load
Get EDOD Failed (initial block) using 640x480@60
Could not find a useful resolution. Maybe hardware problem.
