Hi Peter,
Try this:
USB_DEVFS_PATH=/dev/bus/usb scanimage [...]
The above line tells libusb to look at /dev/bus/usb first. Hope it helps.

You should write the USBID as "4b8/11d/*". (No prepending '0') The environment
variables PRODUCT, DEVICE etc. are defined in the kernel's USB core driver.
(grep 'DEVICE=' [kernel]/drivers/usb/core/*) It is valid for kernel 2.6.13.

libusb 0.1.10a installed in SUSE Linux 10.0 looks at /proc/bus/usb first
then /dev/bus/usb. Whether a newer version also works this way, I don't know.
I think, it also depends on Linux distribution. Actually, the whole problem
is not directly related to SANE. IMHO, distributors should be responsible for
a working libusb.
