SANE vs USB scanner on 8.0

[Daniel O'Connor]

Hi,
I'm trying to get a USB scanner to work with FreeBSD 8.0, it did work 
with 7.2 via uscanner.

It's an AcerScan 620U and I have the firmware and 
modified /usr/local/etc/sane.d/snapscan.conf.

sane-find-scanner sees it, eg
[midget 22:37] ~ >sudo sane-find-scanner  -q
found USB scanner (vendor=0x04a5 [Color], product=0x2060 [ FlatbedScanner 13]) at libusb:/dev/usb:/dev/ugen0.5
found USB scanner (vendor=0x0403 [FTDI], product=0xee18 [MaxStream PKG-U]) at libusb:/dev/usb:/dev/ugen1.2

I have no idea why the FTDI serial device appears there..

However scanimage -L doesn't show the scanner..
[midget 22:40] ~ >sudo env SANE_DEBUG_SNAPSCAN=255 scanimage -v -v -L
[sanei_debug] Setting debug level of snapscan to 255.
[snapscan] sane_snapscan_init
[snapscan] sane_snapscan_init: Snapscan backend version 1.4.53
[snapscan] add_usb_device(libusb:/dev/usb:/dev/ugen0.5)
[snapscan] add_usb_device: Detected (kind of) an USB device
[snapscan] snapscani_usb_open(libusb:/dev/usb:/dev/ugen0.5)
[snapscan] snapscani_mutex_open: could not parse device string: No such file or directory
[snapscan] snapscani_usb_open: Can't get semaphore
[snapscan] add_usb_device: error opening device libusb:/dev/usb:/dev/ugen0.5: Invalid argument
[snapscan] sane_snapscan_get_devices (0x7fffffffe200, 0)

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
Calling sane_exit
[snapscan] sane_snapscan_exit
scanimage: finished

Anyone have any suggestions?
