There are continuous feed scanners. Plenty exist in the office-copier
form factor, some are desktop models (HP high-capacity document
scanners), and plenty are photograph scanners. Ages ago you could get
a sheet feed scanner that mounted on top of a keyboard (or just sat
alone), a 2"x10" cylinder
I understand the CCD/CIS distinction -- I wasn't planning on moving the
light adjacent to the scan head, just thinking about what sort of extra
lighting might be necessary.
I found some older models of the Corex Cardscan that seem pretty cheap
and hackable, but I can't find the 800 model.

Have taken a look at the libusb/darwin.c code, and as far as I can see,
usb _interrupt_ read sequences do not support a timeout. Timeouts are
only used for normal read or write operations.
Now I understand the meaning of the last message that appears in your
logs:
"USB pipe is an interrupt pipe. T
sounds like a solution looking for a problem :) Try searching the
mailing list archives for 'music' - this idea comes up occasionally.
read up on CIS vs CCD machines before you decide to mess with the
light source. I would also suggest you expand your search to include
ADF machines.

Hey Allan + everyone,
I had a scanner, but I took it apart to understand it at a hardware
level... I took it too far (to the point of needing to generate clock
signals for the scan head, etc.) I'd much rather work at a software
level than reverse engineering the scan head.
I would remove the r
sane is not the problem, but rather, which scanner? many of them
produce ugly scans if they are not calibrated, and many of them have
the red/green/blue read-heads offset from one another so that they
cannot produce a scan of a single line. many of them will choke if
they cannot move the read head.

Hi,
Just a quick line to see if anyone knows when this will be
accomplished? It seems this has been going on for quite a while.
CanoScan 8600F USB 0x04a9/0x2229 Unsupported GL841 based, to be
added to genesys backend
Thanks,
Charles.

I am limited by my ISP to 20 MB of web space. I can put the old logs
back up, but that means having to take down the most recent ones.
