[sane-devel] Problem with Acer 640UT, worked before

[Matts]

I have had this scanner working fine in a previous Mandrake and sane version. What happens after a compleete system upgrade is that xsane searches for units forever at start. I have upgraded Mandrake 8.2's sane 1.0.7 to 1.0.8, but the same problem exactly was there before the upgrade too. 

My devices list looks like this:

T:  Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#=  1 Spd=12  MxCh= 2
B:  Alloc= 17/900 us ( 2%), #Int=  1, #Iso=  0
D:  Ver= 1.00 Cls=09(hub  ) Sub=00 Prot=00 MxPS= 8 #Cfgs=  1
P:  Vendor=0000 ProdID=0000 Rev= 0.00
S:  Product=USB UHCI Root Hub
S:  SerialNumber=1020
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=  0mA
I:  If#= 0 Alt= 0 #EPs= 1 Cls=09(hub  ) Sub=00 Prot=00 Driver=hub
E:  Ad=81(I) Atr=03(Int.) MxPS=   8 Ivl=255ms
T:  Bus=01 Lev=01 Prnt=01 Port=01 Cnt=01 Dev#=  2 Spd=12  MxCh= 0
D:  Ver= 1.00 Cls=ff(vend.) Sub=ff Prot=ff MxPS= 8 #Cfgs=  1
P:  Vendor=04a5 ProdID=2040 Rev= 1.00
C:* #Ifs= 1 Cfg#= 1 Atr=40 MxPwr=100mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=ff(vend.) Sub=ff Prot=ff Driver=usbscanner
E:  Ad=81(I) Atr=02(Bulk) MxPS=  64 Ivl=  0ms
E:  Ad=02(O) Atr=02(Bulk) MxPS=   8 Ivl=  0ms
E:  Ad=83(I) Atr=03(Int.) MxPS=   8 Ivl= 16ms

and my /etc/sane.d/snapscan.conf like this:
cat /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 /mnt/windows/windows/usbbin/u64v119.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

And I have a symlink:

[root at localhost root]# ls /dev/scanner -l
lr-xr-xr-x    1 root     root           17 jul 18  2002 /dev/scanner -> /dev/usb
/scanner0


and /dev/usb/scanner0 does exist, when the scanner is plugged in.
