To start with, before ehci-pci.ko was loaded there should have been no usbmon/3u or usbmon/4u files, so your cat commands should have failed. Those filenames correspond directly to the USB bus numbers, and your lsusb output shows only buses 1 and 2. For another, the device numbering is off. On bus 3, device 1 is the root hub and device 2 is the integrated hub -- fine. But then the Foxconn and Ricoh devices should have been numbers 3 and 4, not 6 and 7. Clearly something happened before you started your monitoring. Also, your usbmon3 trace shows the webcam working after it was initialized using the old scheme! It's pretty hard to tell what that means, though, especially since the actions shown in the trace probably weren't the first time the webcam had been initialized since the last cold reboot. -- You are receiving this mail because: You are watching the assignee of the bug.
