I have RedHat 8.0 installed, when I run scanimage I get the following result:

[root@shodan sane.d]# scanimage -d hp:/dev/usb/scanner0
scanimage: open of device hp:/dev/usb/scanner0 failed: Invalid argument

I have compiled and installed sane-backends-1.0.12 and used the 
sane-1.0.9.hp.1.01 source.

The scanner is detected at /dev/usb/scanner0:

[root@shodan sane.d]# sane-find-scanner
# Note that sane-find-scanner will find any scanner that is connected
# to a SCSI bus and some scanners that are connected to the Universal
# Serial Bus (USB) depending on your OS. It will even find scanners
# that are not supported at all by SANE. It won't find a scanner that
# is connected to a parallel or proprietary port.

# If your scanner uses SCSI, you must have a driver for your SCSI
# adapter and support for SCSI Generic (sg) in your Operating System
# in order for the scanner to be used with SANE. If your scanner is
# NOT listed above, check that you have installed the drivers.

sane-find-scanner: found USB scanner (vendor = 0x03f0, product = 0x0101) at 
device /dev/usb/scanner0

But the product string is not reported when i cat /proc/bus/usb/devices:

T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12  MxCh= 0

E:  Ad=83(I) Atr=03(Int.) MxPS=   1 Ivl=250ms

The scanner is a ScanJet4100C.

Where am I going wrong?  Is this a problem with the scanimage?
