Hi,=20

Since some kernel version i can't exactly remember which, i have been
unable to use usb, i have tested with with 2.6.8 -> 2.6.9-rc2-bk7 and i
also applied your patches for 2.6.8.

I have 2 usb dongles, one old that did work once, and one new that seems
to be working like the older but it doesn't work with linux.

Both are based on the CSR chipset, here is the new ones entry from the
hw support list:
MSI MS-6967 CSR 1.1 hci_usb working Dave Beckett

Som logs from insertions:
usb 1-3.4: new full speed USB device using address 12
ehci_hcd 0000:00:02.2: qh f7e54780 (#0) state 1
hci_usb_intr_rx_submit: hci0 intr rx submit failed urb d968cd74 err -28

usb 1-4.4: new full speed USB device using address 13
ehci_hcd 0000:00:02.2: qh f7e54900 (#0) state 1
hci_usb_intr_rx_submit: hci1 intr rx submit failed urb d315eef4 err -28

both of these are connected to usb 2.0 hubs (this machine does usb 2.0)

Output from hciconfig:

write(1, "Can\'t init device hci0. Input/ou"..., 46Can't init device

) =3D 46

Basically, it just stopped working and i dunno why, any clues? at all?
