[sane-devel] Information about unsupported UMAX Astra 4600

[MP]

I manage to have UMAX Astra 4600, that happen to be one of unsupported
models. I noticed that there is no info on
http://www.sane-project.org/sane-mfgs.html about this model, so I hope
this will be useful.

It is USB scanner, vendor id 0x06dc, product id 0x0012, from lsusb:

Bus 005 Device 002: ID 06dc:0012 Foxlink Image Technology Co., Ltd
Scan 1200c Scanner

There are two bigger chips inside, marked as:

REALTEK RTS8801C2-6
and
GLT44016-35J4

Hope that helps. If you think some further information/testing would
help, tell me.
