    Subject[bug?] usb device ok with ohci, fails to accept an address with uhci
    Hi,

    I have a sweex usb-wifi stick see also
    http://sourceforge.net/projects/linux-lc100020/ and it's forums.
    And I have 2 machines
    Machine 1: Via kt133a chipset -> uhci_hcd
    Machine 2: Sis 748 Chipset -> ohci_hcd

    The device works without a problem on machine 2 with at least kernels
    2.6.6 and 2.6.7.
    The usb wifi stick fails to accept an address on machine 1. There is a
    good faq about it with things you can try. (turn off acpi, irq for usb,
    no irq sharing, removing all pci cards,etc) I tried everything but with
    no luck.
    I tried kernels 2.4.26 till and including 2.6.7 without luck, however on
    the same machine is also connected an usb joystick that works without a
    problem, so my usb does work.

    The usb wifi stick is known to need to get a descriptor before settings
    it's address but even with this patch I can't get it to work ( I didn't
    need the patch for machine 2).

    I read some usb specs/docs kernel usb stuff, but since I'm no expert I
    cannot see where the problem is, therefore posted below is some
    information that hopefully is helpfull to you.

    Please let me know what else I can do to help,

    Tommy
