[sane-devel] fujitsu 5120c problem with usb address

[tobias alarcon]

Hi all,

Me again, this time its really strange problem
When i connect the usb, and run scanimage -L

"fujitsu:libusb:005:002"

but when i run my front-end i get this message from /var/log/syslog

Mar 25 15:36:33 localhost kernel: usb 3-3: USB disconnect, address 2
Mar 25 15:36:48 localhost kernel: usb 3-3: new high speed USB device
using ehci_hcd and address 3
Mar 25 15:36:48 localhost kernel: usb 3-3: configuration #1 chosen from 1 choice
Mar 25 15:37:10 localhost kernel: ppdev0: no associated port!

so my program it never able to find the scanner. And every time i run
happen the same,
with a diferent usb address.
It happen on two diferent computer with the same version of
sane-backend (1.0.18)
with two diferent scanner (same model obviously)

i really don't know what could be. I read on the internet and some
people say it can be
the firmware? i really don't know.

Please any help will be apreciated.
thanks

Tobias
