USB problem pri pripojeni

[Josef Feit]

Dobry den,

mam iTEC 20GB databanku spojenou s cteckou karet.

Pri pripojeni dostavam hlasky (dmesg):

usb 6-1: new full speed USB device using uhci_hcd and address 13
usb 6-1: device descriptor read/64, error -71
usb 6-1: device descriptor read/64, error -71
usb 6-1: new full speed USB device using uhci_hcd and address 14
usb 6-1: device descriptor read/64, error -71
usb 6-1: device descriptor read/64, error -71
usb 6-1: new full speed USB device using uhci_hcd and address 15
usb 6-1: device not accepting address 15, error -71
usb 6-1: new full speed USB device using uhci_hcd and address 16
usb 6-1: device not accepting address 16, error -71
hub 6-0:1.0: unable to enumerate USB device on port 1

a databanka se nepripoji (neobjevi se novy /dev/sd*, neni nic
noveho v /dev/disks/by-id)

Databanku jsem drive pripojoval normalne, ted jsem zkousel
FC6 (funguje) a openSuse 11 (stejny OS co mam ja, ale jiny pocitac)
a funguje to.

Reseni, ktera jsem nasel, nezabiraji:
vadny kabel - jinde funguje normalne, drive fungoval
modprobe -r ehci_hcd  nepomuze

Zkousel jsem to pripojit na USB port na pocitaci zezadu, dale do 
(fungujiciho) USB hubu, vysledek je stale stejny. Jina USB zarizeni 
funguji.

Nevi nekdo, na co se jeste podivat?

diky,
JF
