Tried the workaround wrapper link J.Rinas posted to this discussion? It
works fine for me.
The USB_SUSPEND is intended for laptop users and anyone else who wants to
run their workstations in an energy-efficient way.
What it's doing to scan apps is a bug, the feature needs to be fixed, not
removed.

Hi all,
I just had the same problem with my Canon 630U - when using the Debian
Kernel 2.6.22-1-k7 with having USB_SUSPEND enabled the scanner isn't
working any more, the kernel is printing dozends of:
#
usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd xsane rqt 64 rq 12 len 1 ret -71
#
usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd xsane rqt 64 rq 12 len 1 ret -71
#

#

#
usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd xsane rqt 64 rq 12 len 1 ret -71
#

#
usb 2-2: usbfs: USBDEVFS_CONTROL failed cmd xsane rqt 64 rq 12 len 1 ret -71
Recompiling 2.6.22-1-X without having enabled USB_SUSPEND fixed it, the
scanner is working properly again.
Are there any reasons to use this experimental feature in the Debian
kernels?
Regards, Joerg.
