[sane-devel] loosing contact to scanner
Wed, 22 May 2002 18:27:48 +0200
i have successfully (seemingly) installed my snapscan e40 agfa
scanner to my redhat linux 7.2 system. and i'm able to scan
images as long as i like. but overnight, the system seems to
the next day, when i try it again, when xsane tried to find the scanner,
the green light on the front just flashes on and off for 5 or 10 minutes
then quits. i.e., overnight i leave the system running, (the scanner
no on/off switch) and i leave xsane running, simply walk away from the
system for 10 hours or so
here is the contents of /proc/bus/usb/devices when this has occured.
Notice the I: line. Driver=hub. i belive it used to be
while it was scanning correctly.
[jimka@localhost usb]# cat /proc/bus/usb/devices
T: Bus=01 Lev=00 Prnt=00 Port=00 Cnt=00 Dev#= 1 Spd=12 MxCh= 2
B: Alloc= 0/900 us ( 0%), #Int= 0, #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
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
anyone have an idea what is happening, and how i can fix it short
of rebooting every day?
