[sane-devel] python-sane - checking for active device
subscriptions at gnumed.net

What is the correct way of checking whether a device is available (plugged in,
switched on) using the python SANE interface?
If I switch my scanner off, sane.get_devices(), sane keeps reporting the
scanner as if it was still available.
If I start the program with the scanner switched off, and switch it on *after*
calling sane.get_devices(), no scanner is found.
Doing a sane.exit(); sane.init() prior to calling sane.get_devices() makes no
What am I missing or doing wrong?
Thankful for any advice,
