I've been following both the USB and the sane list since I bought an AGFA
|
|
<BR>
|
|
snapscan USB scanner. After much testing and fighting, and despite loads of help
|
|
<BR>
|
|
from both groups, I eventually flogged this scanner for a SCSI one. However, I
|
|
<BR>
|
|
do know that there has been success in this area. Namely, David Nelson was able
|
|
<BR>
|
|
to get a few HP USB scanners to work. The solution is two-fold. First, you have
|
|
<BR>
|
|
to get the scanner talking to your PC over the USB port. This is the job of the
|
|
<BR>
|
|
USB driver. This will give you a /dev/usbscanner. Next, you need to get sane to
|
|
<BR>
|
|
talk to your scanner via /dev/usbscanner.
|
|
<BR>
|
|
<P>First point: Have a look @ www.linux-usb.org and get on there mailing list.
|
|
<BR>
|
|
David Nelson has got some HP scanners talking via usb, and with a little
|
|
<BR>
|
|
modification of his code, I had my AGFA talking as well. David was quite helpful
|
|
<BR>
|
|
with this, considering that I'm am not a programmer, he showed me exactly where
|
|
<BR>
|
|
to modify the code and exactly what to change to get it talking. Once you get
|
|
<BR>
|
|
your scanner talking over USB, then you need to work with the sane side.
|
|
<BR>
|
|
<P>Sane side: Now that your scanner is talking over USB, it may not be talking
|
|
<BR>
|
|
SCSI. If you are lucky, as David was with HP, the scanner may use the same
|
|
<BR>
|
|
protocol. Otherwise, you will need to find out what protocol the scanner uses
|
|
<BR>
|
|
over USB. The HP's did use SCSI over the USB port, but, sadly, my AGFA scanner
|
|
<BR>
|
|
didn't. This was why I eventually sold it to my niece, who is using Windows98.
|
|
<BR>
|
|
<P>This will be a major undertaking on your part to get this working. Lots of
|
|
<BR>
|
|
people on both lists will be quite helpful, but you can expect to do quite a bit
|
|
<BR>
|
|
of work, with assistance. IF you can get it working, you can feel quite good in
|
|
<BR>
|
|
yourself for making such a major contribution to Linux. USB and scanners are
|
|
<BR>
|
|
areas that need lots of work. If not, be more careful when buying hardware. I
|
|
<BR>
|
|
know, I've made many mistakes buying hardware only to find that the support
|
|
<BR>
|
|
wasn't there. I am now much more careful to check what is and isn't supported
|
|
<BR>
|
|
before I buy now. I've had to replace a modem, a printer and a scanner. And I've
|
|
<BR>
|
|
gotten loads of grief from the wife each time.
|
|
<BR>
|
|
<P>Good luck with your scanner and I hope you can get it working. Linux need as
|
|
<BR>
|
|
much hardware support as possible. Especially USB.
|
|
<BR>
|
|
<P>Cheers,
