<P>
I know that the status of USB on Linux is questionable. I have been
<BR>
&quot;working&quot; with the linux-usb group for a while (I quote that because I
<BR>
mainly am doing just testing, not coding). David has the scanner
<BR>
driver so that it recognizes my scanner and attaches itself as the
<BR>
driver for that device. Now for getting sane to work...
<BR>
<P>I downloaded sane 1.0.1 and compiled it OK. I wasn't sure how to
<BR>
setup the etc/sane.d/umax.cof file but guessed anyway. Here is what I
<BR>
put:
<BR>
scsi UMAX * Scanner
<BR>
/dev/usbscanner
<BR>
<P>where
<BR>
<P>crw-rw-rw- 1 root root 180, 48 Jan 20 20:15 /dev/usbscanner
<BR>
<P>This didn't work, xscanimage reports &quot;no devices available&quot;. I tried
<BR>
tools/find-scanner and noticed it only checks the /dev/sg? devices and
<BR>
/dev/scanner. So, I symlinked /dev/usbscanner to /dev/scanner and
<BR>
re-ran.
<BR>
<P>find-scanner: checking /dev/scanner... open ok
<BR>
find-scanner: found disk &quot; &quot; at device /dev/scanner
<BR>
<P>This takes a _very_ long time to run. My question is this, &quot;Is this a
<BR>
usb problem or a sane problem?&quot; Can the umax backend be made to
<BR>
recognize this as not a disk but a scanner?
<BR>
<P>If it's any help, here's the output of /proc/bus/usb/devices:
<BR>
P: Vendor=1606 ProdID=0030 Rev= 1.00
<BR>
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=100mA
<BR>
I: If#= 0 Alt= 0 #EPs= 3 Cls=00(&gt;ifc ) Sub=00 Prot=00 Driver=usbscanner
<BR>
E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
<BR>
E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl= 0ms
<BR>
E: Ad=83(I) Atr=03(Int.) MxPS= 1 Ivl= 1ms
<BR>
<P>Of course, there isn't anything in /proc/scsi/scsi related to the
<BR>
sanner (only my ide cdrw using ide-scsi).
<BR>
<P>Just for grins: Linux kernel 2.3.42, gcc 2.95.2 (19991024), glibc 2.1.1
<BR>
