Hi!

I'm using Debian Sarge 3.1r0a with sane 1.0.13-2 and sane-utils
1.0.16-1, the
Mustek 2400CU Plus scanner. Well, I downloaded the PS2Dfw.usb firmware
file as they say on their homepage, but managed to scan only the
[distorted] half of the page. Then, I tried PS2Dfw2.usb file (diff says
it's identical to what was shipped on the CD), and XSane just hangs for
a short while and gives me 'Invalid argument'! Arrrrrgh!!! I remember
that problem existed in my previous installation, but I can't remember
how I managed to fix it. Any help?

Thanks for the tar.gz of the plustek*.*

Great news - the UIO error is gone - I still get a beep from the PC 
speaker the first time the device is accessed - however I've not seen 
any hangs on 10 or so scans - including unplugging/replugging the 
scanner to try and trigger it.

Thanks for your help!

Cheers,

Paul.
