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

[tobias alarcon]

nop
I will give you more details, so if you can help i will really apreciated
When i stop the power cycle of the scanner, everything goes fine for
about 15 min
then also if i don´t stop to scan pages still works
So the problem begin when stop scaning. The usb address change with no reason
(i don´t disconnect the cable) and don't have any suspend mode on usb devices.
if i call scanimage or my application why the address does not update
if both call
sane_init() at start?

So if a repeatedly call sane_open() this way the scanner belive is
been used for some
application? do you thing this could work?

well thanks in advance.

Tobias.

pd: also have a fujitsu 4110cu. i thing going to write my first backend lol.
