I though I was the source of those rummors. At least the comments on my
web page are just based on the observation that the scanner has both
USB and SCSI interfaces.

Well my reasoning is that I would be stunned if Umax had done anything other
than put a SCSI-to-USB converter chip on the scanner board. Anything else
would be a really dumb thing to do in order to get a USB interface on a
scanner with a SCSI interface.

Certainly nobody has ever reported any success or failure to this list or
myself.
Getting back to the original post, they say that the scanner driver is
recognising the scanner and returns a vendor:product id.
I suspect there is a problem with device files and the umax.conf file.
Check that /dev/usbscanner0 exists and if not create with
mknod /dev/usbscanner0 c 180 48
and then do
ln -s /dev/usbscanner0 /dev/usbscanner
make sure you have suitable permissions on /dev/usbscanner so do
chmod 666 /dev/usbscanner0
Next make sure that umax.conf points to the right device file. It should be
/dev/usbscanner. Note that with my HP5200C you need to add the line
option connect-device
to the hp.conf file, I have no idea if this will be needed for a UMAX scanner.
If this does not work, change the umax.conf to point to the device files
in umax.conf point to the scanner device files in /dev/usb/
I suspect this scanner will work with USB, just nobody has tried, and if
they have got it working they have not said anything about it.
JAB.
