[sane-devel] Problems with Benq S2W 5000E

[Sven Sanwald]

Hello,

with my Benq S2W 5000E I have the problem that after the first half
of the scanned area the scanner stops  with the output:

bash-2.05a# scanimage
[sanei_debug] Setting debug level of snapscan to 2.
[snapscan] add_usb_device: error opening device libusb:001:002: Device busy
[snapscan] calibrate: reading calibration data (2 lines)
Segmentation fault

Same result with xscanimage.

bash-2.05a# scanimage -L
[sanei_debug] Setting debug level of snapscan to 2.
[snapscan] add_usb_device: error opening device libusb:001:002: Device busy
device `snapscan:/dev/usb/scanner0' is a Acer FlatbedScanner25 flatbed 
scanner

here it gives the correct scanner number---------------------------------^^
but when I do:
cat /proc/bus/usb/devices
I receive:
