If I try to queue bulk urbs to an endpoint (2.5, uhci-hcd), I rapidly get "host controller process error. something bad happened" followed by "host controller halted. very bad". In order to track down what went wrong, I would like to know which TD caused the host controller to barf, which QH it is in, which urb it is for etc. The problem is that I don't see how to find out which TD is causing the problem. That information does not seem to be retrievable from the host controller. Any suggestions for how to determine (in uhci_irq for example) where things went wrong?
