Hi,
I've remarked this problem when using the preview:
If I click on "Acquire preview" then, while running, "cancel preview"
I get the following message :
"Backends sends more image data that it defined in parameters"
Then, if I click again on "Acquire preview", I get the message :
"Failed to start scanner: Invalid argument"
I cannot close xsane with the [X] button, I've to kill the task from the
window manager. At this point, xsane is eating most of the cpu ; Only a
"kill -s 15" is able to kill the task.
Then if I start xsane again, it stay in the state "scanning for
devices".
After a while, I get:
usb_control/bulk_msg: timeout
scanner.c: write_scanner: NAK received.
To be able to have the system to work again, I've to do a power off/on
of
the scanner. Sometimes, I get:
"scanner.c: close_scanner(0): invalid scn_minor"
system is :
linux 2.2.20pre (the same occurs with 2.2.19 or 2.4.6-ac).
sane-backends-1.0.5
xsane-0.78
The scanner is an Epson Perfection 1640SU Photo.

Jean-Luc
