Thanks, I'm looking at the logs and so far the most suspicious looking entry is:

[  257.060941] rtsx_usb-254     0.... 119946155us : xhci_urb_enqueue: ep1out-bulk: urb ffff880105a93300 pipe 3221259520 length 0/12 sgs 0/0 stream 0 flags 00010000
[  257.063601] rtsx_usb-254     0.... 119946162us : xhci_urb_enqueue: ep0out-control: urb ffff880105a93300 pipe 2147484928 length 0/0 sgs 0/0 stream 0 flags 00100000

It enqueues the same URB, without ever giving it back or actually queuing any trbs for
the urb, wel,l it might just fail to enqueue it in the first place.

I need to search for a URB that has been dequeued but never given back in the trace
