[sane-devel] OS X/Umax 1220u not recognized

[David Minor]

I'm struggling to get my 1220u setup with SANE.

$ sudo sane-find-scanner
found USB scanner (vendor=0x1606, product=0x0010) at libusb:025:003
(most of the time.  sometimes says no usb scanner found)

$ sane-find-scanner
No USB scanners found.

$ scanimage -L (as root or user)
No scanners were identified

OS X (10.2.8)
TWAIN/SANE interface 0.2
SANE backends 1.0.13
libusb 0.1.8 beta
(all packages from Mattias Ellert)

the vendor/product IDs above are in sane-umax1220u.conf and I've also 
tried adding them to sane-umax.conf.

Anyone have any ideas as to where the problem might be?

below is the output from sane-find-scanner -v -v:
