Quick question:
Are there known problems with sane 1.0.1, SCSI scanners and the pt
driver under 3.1 STABLE?
I have HP ScanJet 4c, configured as pt0:
w3proj3# camcontrol devlist -v
...
<HP C2520A 3503> at scbus0 target 5 lun 0 (pass2,pt0)
...
w3proj3# ll /dev/pt0
crw-rw---- 2 root wheel 61, 0 May 26 16:12 /dev/pt0
I hardlinked /dev/pt0 to /dev/scanner
However, trying to run "scanimage" from the "sane 1.0.1" port results
in:
w3proj3# scanimage -d hp
scanimage: open of device hp failed: Invalid argument
I did a "ktrace" on scanimage and found the following:
...
5428 scanimage CALL open(0xefbfc6f8,0x2,0x280b6a8c)
5428 scanimage NAMI "/dev/scanner"
5428 scanimage RET open 5
5428 scanimage CALL ioctl(0x5,CAMGETPASSTHRU,0xefbfc004)
5428 scanimage RET ioctl -1 errno 19 Operation not supported by device
5428 scanimage CALL madvise(0x8057000,0x1000,0x5)
5428 scanimage RET madvise 0
5428 scanimage CALL madvise(0x8056000,0x1000,0x5)
5428 scanimage RET madvise 0
5428 scanimage CALL close(0x4)
5428 scanimage RET close 0
5428 scanimage CALL madvise(0x804e000,0x2000,0x5)
5428 scanimage RET madvise 0
5428 scanimage CALL write(0x2,0xefbfd418,0x36)
5428 scanimage GIO fd 2 wrote 54 bytes
"scanimage: open of device hp failed: Invalid argument
"
5428 scanimage RET write 54/0x36
...
"Not supported by device" doesn't sound good to me. Isn't the pt driver
supposed to be used for scanners?
The scanner worked under 2.2.8 and sane 0.something
Any hints appreciated.
