Last modified: 2007-11-30 17:07:02 EST
Description of problem: I performed a fresh install of Redhat Enterprise WS, with a USB scanner plugged in and turned on. Xsane does not recognize the scanner Epson Perfection 1640 SU. When I attempt to configure the scanner I get the folloing message "no devices available". Version-Release number of selected component (if applicable): Redhat Enterprise WS version 3 How reproducible: 100% Steps to Reproduce: 1. In Redhat GUI click Main Menu > Graphics > Scanning > Accept. Error message: "no devices available". 2. Then at a console type "sane-find-scanner". The scanner is found but not recognized. Here's the resulting message: Actual results: ---------- # sane-find-scanner # No SCSI scanners found. If you expected something different, make sure that # you have loaded a SCSI driver for your SCSI adapter. found USB scanner (vendor=0x04b8, product=0x010a) at /dev/usb/scanner0 found USB scanner (vendor=0x04b8 [EPSON], product=0x010a [Perfection1640]) at libusb:002:005 # A USB device was detected. This program can't be sure if it's really # a scanner. If it is your scanner, it may or may not be supported by # SANE. Try scanimage -L and read the backend's manpage. # Scanners connected to the parallel port or other proprietary ports can't be # detected by this program. Expected results: Recognition and automatic configuration of scanning device. Additional info:
Not a bug. Scanners do not have a device class, they are always determinded by the vendor:product ID. Because of this, it's a losing battle to add those. Use options vendor= and product= in /etc/modules.conf. N.B. Contemporary SANE backends work through libusb and have their own vendor:product lists. The kernel scanner driver will be discontinued in the next release of the RHEL (already discontinued in FC2).
