It can find the scanner but can't open it because it was already claimed by the USB scanner driver.

I don't think the problem is related to the "Device Busy" message but to make sure, do "rmmod scanner" and try again. You may need to set up permissions for usbfs (see man sane-usb) to get that working. Now you should be able to scan using libusb instead of the kernel scanner driver. If the same error occurs, it looks like a backend problem. Otherwise, it may be a problem with the kernel scanner driver or sanei_usb. Bye, Henning
