[sane-devel] Umax Astra 4000U and sane-umax

[Nissim Chudnoff]

Hello,

I'd love to help get this scanner supported in SANE with the umax-sane
driver. I hope there are people who might find this useful, do you
know if anyone else is working on this? Unfortunately, this is my
first time using anything USB in Linux so hopefully I haven't botched
something simple.

The 4000U has Vendor 0x1606 and Product 0x1030. Inside there's a
Powervision PV8630DL, Winbond W6662CF, the unlabeled main chip
(13010059-5000), and some kind of ROM labeled "Astra 4000U U1
V1.1".

I installed USB in kernel and "scanner" as a module with the options
for the Astra 4000U.

I comment out the scsi scanners and the 2200U lines in the sane-umax
config, and add 0x1606 0x1030. Set debug to 13 and run scanimage:

Is this indicating a problem with how I've (mis)configured USB or is
there something I can do to the sane-umax driver to force it to talk
to the 4000U? I'd be more than glad to do any testing for anymore more
familiar with SANE...

Thanks,
