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
