Hello!
Going on a limb here - faulty USB cable causes USB resets which throws
off legacy emulation (which is done in SMM as well as KBC controller)
which causes KCB to lose bytes. I would expect also seeing some
keypresses not being registered but losing release is much more
visible...
It's possible. But the USB drivers try to take control of the host
controllers away from the SMM BIOS. How could legacy support work with
both SMM and the Linux USBHID system trying to handle it?
Please tell me what I can do to help to debug this strange behaviour.
Repuducing the USB resets is easy, but reproducing the PS/2 influence
takes long, since its hardly visible.
many regards,
claas
