I have an HP 5100C parallel port scanner that I'm trying to get working. I installed the ppscsi driver, and scanimage recognizes the device, but it won't complete a scan.
I run scanimage with the command scanimage -d hp:/dev/sg0 > testscan Then X freezes for a few seconds while the scanner makes noises, then the noises stop and X unfreezes, and after a few more seconds, scanimage returns with the message: scanimage: sane_read: Error during device I/O Here is the relevant part of /var/log/messages: Aug 4 01:48:28 kuching kernel: epst.0: epst 0.92 (0.92), Shuttle EPST at 0x378 mode 0 (Nybble) dly 0 nice 0 sg 0 Aug 4 01:48:28 kuching kernel: scsi0 : epst Aug 4 01:48:28 kuching kernel: Vendor: HP Model: C5190A Rev: 3740 Aug 4 01:48:28 kuching kernel: Type: Processor ANSI SCSI revision: 02 Aug 4 01:48:28 kuching kernel: Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 3 Aug 4 01:49:10 kuching kernel: epst.0: PDMA done timeout, bs=31 cb=6 db=32768 bu=1 sg=0 rd=1 lp=31 pe=0 cc=922 Aug 4 01:49:10 kuching kernel: epst.0: Arbitration failure, bs=31 cb=0 db=32768 bu=0 sg=0 rd=1 lp=0 pe=0 cc=923 Aug 4 01:49:51 kuching kernel: epst.0: Bus reset It could be possible that this is a hardware problem. I got the scanner for free and was told about a minor glitch that sounded hardware-related. Thanks, Ben
