Thank you for all your responses.

I'm using Debian unstable, kernel 2.6.6 with ohci_usb, libusb-0-1.4 (0.1.8-11). The scanner is an Epson Perfection 2450.

It seems libusb isn't working as it should - maybe future Debian updates will solve the problem; in the meantime I am happy with my hack, but if anyone would like me to try out some suggestions to get to the bottom of this mystery, I'd be happy to help off-list.
