[sane-devel] HP Scanjet 3P io errors

[jd]

I found nothing related in the archives:

Using sane front & back ends v1.0.7

Device is Scanjet 3P and ADF, model 2570A, firmware 3430.
Connected to Buslogic BT946C.

sane does not seem to like my scanner. It returns io device errors.
Works fine with epson scanner.

Using RedHat 7.3, latest & lastest updates.

 From dmesg:

        (Manually insmod'd scsi_hostadapter later. But it makes no 
difference whether it is loaded or not.)


sane-find-scanner detects the device at /dev/sg0

sane -d hp:/dev/sg0 *(any command or option)   returns "Error during 
device I/O" and the help page.
THis occurs with or without option dumb-read

 From /etc/sane.d/hp.conf: (RedHat's default location)

    scsi hp
        option dumb-read
    /dev/sg0
   
 From another form of hp.conf:

    scsi HP C2570A Processor 0 00 00 00
    option connect-scsi
    option dumb-read

hptool's hpinq returns the model number and firmware code but then 
returns nothing but io errors on stderr and
"error in inquiry" for each command.


This scanner works with windoze.

I have no idea what is going on. Does anyone?

Thanks...
