that is a good idea! if I can be of any help please let me
know.
I thought about it myself, but never found time for that
(and most
likely neither will anytime soon, so please go ahead!).

Hi Andrey,
thanks for the patch, commited. I hope it doesn't cause side
effects.
the proble with usb reset is that the device will get a new
device
number on the usb bus, and thus the old openct ifdhandler
will need
to die and exit, and udev will spawn a new one for the new
device.
so usb reset is like unplugging and plugging in again.
except for the
absolute worst case scenario it should never be necessary to
do that.
Andreas
