Hello Kevin,

Just a quick first reaction. This log is already including the patch you are referring to.

I will be looking into the other items as well and provide a response as soon as I have this information.

Best regards, Wim

Thanks.  It looks like you have a few modifications to the source code
- that's fine, but it makes it hard to line up the debug messages to the code I have - can you obtain the same logs using the latest seabios from the master branch of the seabios git repo?  ( git clone git://git.seabios.org/seabios.git )

Also, can you provide the output of "lspci" and "lsusb -v" in the working setup and the output of "lsusb -t" in both the working and non-working setup?

My initial reaction is that it seems similar to previous xhci reports of devices renegotiating to super speed after initially being detected as high speed.  Can you also test with the patch at:
