In other words, = the problem is in the xhci-hcd driver, and it has no connection to the commit y= ou found. Except perhaps that increasing the time delay manages to avoid the = bug somehow. You can try enabling dynamic debugging for xhci-hcd. On the boot command l= ine, add: dyndbg=3D"module xhci_hcd =3Dp" and see what shows up in the dmesg log. --=20 You may reply to this email to add a comment.
