perhaps no.
and what is happening in your situation when you switch it off while cgminer is running?
working with overclocks and its bothersome having to stop all mining to test a individual gridseed :p
I have now been asking and asking again and again, I WISH I new how to code and devlope I would be the guy who takes over Cgminer for the grids!, I have spotted a few Bugs..
When I have over 25 Grids plugged using the the updated Cgminer which has capabilities for the blade and also has the send work write error LIBUSB timeout CGMINER IS NOW CLOSING
There also should be a way to have all your miners plugged in and when you start cgminer they all showup without that plug in Once started crap... I cannot beleive 2 months after release and still not a good release is out
CAn someone PLEASE help or direct me to the write place if there is development going on
