hi, after my scanner has been on for a couple of days, including xsane running the entire time. no restart, no reboot.
a scanner is still found in /proc/bus/usb/devices (see below), but sane-find-scanner can no longer find it, and xsane can no longer connect to it. and after sane-find-scanner no longer finds the scanner, then /proc/bus/usb/devices no longer knows what kind of scanner it is. notice earlier the lines S: Manufacturer=AGFA S: Product= SNAPSCAN e40 appear in /proc/bus/usb/devices, but afterward they no longer appear there.... NOT EVEN modprobe scanner vendor=0x06bd product=0x208d fixes the problem. i believe it starts working again, if i reboot and then run modprobe scanner vendor=0x06bd product=0x208d -jim 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=d400 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.)
