I only run these on bare metal. What I assume so far is that when
rt2x00usb_vendor_request starts failing like this, the MCU has failed.
Power cycling the system helps but is undesirable, and sometimes so
does a forced removal of rt2800usb, a short recovery period (cooling
down, reloading the firmware?) and then loading the module again.
But the problem I am looking to solve is not a hardware problem, it is
recovering gracefully from a failure in the RT5592, so I have been
looking intently at rt2x00usb_vendor_request because that's the
function that complains loudly and kills the entire kernel when the
RT5592 sees this failure.
Kind regards,
jer
