Trying to update the Omega PS150's firmware in response to the drown attack vulnerability. Previously the .bat file ran and loaded the firmware on the thumbdrive, but in this case I get an error saying it can't find the USB flash drive. Any trick to this. I've followed the directions in the command prompt, so the drive isn't in when the .bat file is first run.Loading off a Win 7 machine. Haven't tried a workstation with Win 10 yet or Win server. .
