Hi Marx
The only thing I can think of is the firmware for dual ite 9135(9006)
chip version 1 may be different.
Make sure you only scan on adapter 0 on ehci.
If you want to send me privately a copy of the IT9135BDA.sys file
from /WINDOWS/system32/drivers directory. I can extract and test that
firmware against the devices I have and eliminate the Linux driver.
Regards
Malcolm
