-# There seems to be either a bug or a feature which renders the scanner unusable if 
-# there were too many attemps to establish TLS connection with it. While device
-# seems to magically fix itself after a while (8 hours?) it is extremely annoying
-# when hacking.
-#
-# It is probably not that bad if all communication is done by a single service process which
-# only initiates TLS connection once during system startup and then simply serves
-# requests via DBus, DCOM or whatever. It is not that nice when you have a 
-# standalone program which you are hacking and restarting all the time.
-#
-# So, to workaround the problem I'm trying to save and restore the TLS state
-# between the prototype invocation. This works fine with one exception. As soon as 
-# you close the last file descriptor associated with a USB device, the kernel automatically
-# resets the device, effectively killing the established TLS state.
-#
-# This script helps to work around this last problem. It keeps an open descriptor which 
-# prevents kernel from resetting the device configuration. It does not interfere with
-# the main process and does not hold the claim on the inface. It just sits there
-# doing nothing until you decide to quit.
-#
-# The same can be achived by running something like "read 4</dev/bus/usb/001/011" from
-# a command line, but in this case you need to figure out what is the current bus/device 
-# number yourself.
