I just got some information from sane-development-list

Subject: Re: [sane-devel] LIde 20 scanner & kernels newer than
 2.6.20-9 (snip)

I'm using backend with no problems in kernel 2.6.20 disabling such
option. Most backends use libusb to establish communitation between device
and PC. Libusb doesn't provide functions to check that condition. May be
I'm wrong but If it's not a kernel problem (USB_SUSPEND is yet experimental)
I think that problem must be fixed in libusb libraries.

I an going to file this with libusb & point to this bug.
