Thanks again, I was just reading the note about "Model B Hardware Revision 2.0 and Revision 1.0 with ECN0001 change" in the RPi VerifiedPeripherals wiki.
If I'm just using the full USB end of the USB-micro cable, and plugging in to one of USB female ports on the PI, then I don't think there should be any issues since this would be high impedence and no draw. Any 5v on the PI end wouldn't hurt the Flir either?
With the correct drivers, I should be able to grab the twain or stream from the Flir and capture at some size and framerate according the script I use.
*i think*
Thanks again for youe time and efforts!
Cheers
