For what it's worth, I appear to be in exactly the same
situation as Torfinn, with my snapscan-e20. I've now run the
back-end with the SANE_DEBUG_SNAPSCAN env set to 255, and it is
clear that it is running into the same device string parsing
[sanei_debug] Setting debug level of snapscan to 255.
[snapscan] sane_snapscan_init: Snapscan backend version 1.4.53
[snapscan] add_usb_device: Detected (kind of) an USB device
[snapscan] snapscani_mutex_open: could not parse device string: Invalid argument
[snapscan] snapscani_usb_open: Can't get semaphore
[snapscan] add_usb_device: error opening device libusb:/dev/usb:/dev/ugen0.3: Invalid argument
[snapscan] sane_snapscan_get_devices (0x7fffffffcbe0, 0)
I'll see if I can help with the bug reportage. I know scanners
are inexpensive (this one was), but it used to work very nicely
for my purposes, so I'd like to un-break the software, by
