Once the firmware upload to the scanner has=20 completed (see below) I can do any number of scans. Tested on FreeBSD=20 4.5, UHCI, Acer 620UT, xsane 0.85. There is a problem with the firmware upload - the backend hangs after=20 the firmware upload is completed and has to be killed (-9). However,=20 since the firmware upload is only made if necessary, any subsequent=20 starts of Sane work fine. If you want me to run any specific tests let me know. Regards, Oliver
