    SubjectRE: 3.1.5: uvcvideo: Failed to resubmit video URB (-27).

    From: Andrew Burgess [mailto:aab@cichlid.com]

    it sounds like a bug recently tracked down on the usb devel list
    (search for 'Failed to resubmit video URB')

    it turned out to be a bug in the usb host controller; if you
    do an lspci do you see anything made by NetMos or MosChip?

    mine says:

    0b:00.0 USB Controller: NetMos Technology MCS9990 PCIe to 4‐Port USB
    2.0 Host Controller

    mine is a pcie card; perhaps you have one built in?

    It’s a bit different for my model:
