I'm having the similar (but not identical) difficulty with a Benq (Acer) 3300U that worked perfectly under Red Hat 7.1. After upgrading to Red Hat 9.0 and the latest SANE packages (compiled, not Red Hat packages) I get the following behavior: Looking in /proc/bus/usb/devices I find: ===================begin /proc/bus/usb/devices listing============= E: Ad=01(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms E: Ad=82(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms T: Bus=01 Lev=02 Prnt=02 Port=02 Cnt=02 Dev#= 3 Spd=12 MxCh= 0 D: Ver= 1.00 Cls=ff(vend.)

According to the Sourceforge page (http://snapscan.sourceforge.net/), the Acer/Benq 3300 uses either the "u222v067.bin" or "u176v046.bin" firmware files. Looking at the CD that came with the scanner I find the first one (u222v067.bin), but not the second one: ===================begin listing of CD firmware================== /mnt/cdrom1/u174v041.BIN /mnt/cdrom1/u176v042.bin /mnt/cdrom1/u222v067.bin /mnt/cdrom1/u34v110.bin /mnt/cdrom1/u96v121.bin ===================end listing of CD firmware==================== I copied the "u222v67.bin" file to /etc/sane.d/firmware/Benq_3300U and modified the /etc/sane.d/snapscan.conf file as shown below: ===================begin /etc/sane.d/snapscan.conf================ #------------------------------ General ----------------------------------- # Change to the fully qualified filename of your firmware file, if # firmware upload is needed by the scanner firmware /etc/sane.d/firmware/Benq_3300U/u222v067.bin # If not automatically found you may manually specify a device name. # For USB scanners also specify bus=usb, e.g. # /dev/usb/scanner0 bus=usb # For SCSI scanners specify the generic device, e.g. /dev/sg0 on Linux. # /dev/sg0 #--------------------------------------------------------------------------- # No changes should be necessary below this line #--------------------------------------------------------------------------- #-------------------------- SCSI scanners ---------------------------------- # These SCSI devices will be probed automatically scsi AGFA * Scanner scsi COLOR * Scanner scsi Color * Scanner scsi ACERPERI * Scanner #--------------------------- USB scanners ----------------------------------- # These USB devices will be probed automatically # (This will currently work only on Linux) # Benq/Acer/Vuego 320U usb 0x04a5 0x2022 # Benq/Acer/Vuego 620U / 620UT usb 0x04a5 0x1a2a usb 0x04a5 0x2040 # Benq/Acer/Vuego 640U usb 0x04a5 0x2060 # Benq/Acer/Vuego 640BU usb 0x04a5 0x207e # Benq/Acer/Vuego 1240U usb 0x04a5 0x20c0 # Benq/Acer/Vuego 3300 / 4300 usb 0x04a5 0x20b0 # Benq/Acer/Vuego 4300 usb 0x04a5 0x20de # Benq/Acer/Vuego 5000 usb 0x04a5 0x20fc # Benq/Acer/Vuego 5300 usb 0x04a5 0x20fe # Agfa 1236U usb 0x06bd 0x0002 # Agfa 1212U usb 0x06bd 0x0001 usb 0x06bd 0x2061 # Agfa Snapscan e10 usb 0x06bd 0x2093 # Agfa Snapscan e20 usb 0x06bd 0x2091 # Agfa Snapscan e25 usb 0x06bd 0x2095 # Agfa Snapscan e26 usb 0x06bd 0x2097 # Agfa Snapscan e40 usb 0x06bd 0x208d # Agfa Snapscan e42 usb 0x06bd 0x20ff # Agfa Snapscan e50 usb 0x06bd 0x208f # Agfa Snapscan e52 usb 0x06bd 0x20fd ===================end /etc/sane.d/snapscan.conf================== If I run Xsane at this point it hangs.
