https://bugzilla.kernel.org/show_bug.cgi?id=207887 --- Comment #16 from Alan Stern (stern@xxxxxxxxxxxxxxxxxxx) --- This looks like a problem with the xHCI host controller or driver. You can do two things to help debug it: Turn on dynamic debugging for the xhci-hcd driver: echo 'module xhci_hcd =p' >/sys/kernel/debug/dynamic_debug/control Collect a usbmon trace: cat /sys/kernel/debug/usb/usbmon/3u >mon3.txt & Kill the cat process after an error occurs. Let's see what the debugging messages and usbmon trace reveal. -- You may reply to this email to add a comment. You are receiving this mail because: You are watching the assignee of the bug.
