(btw, the light is supposed to stay on)
(thx for the info on the light, I read another thread where someone said that the light staying on means it's throttling)
You should powercycle it, then verify that the firmware took using easyminer (right click, info).v It should say firmware integrity check passed, and show a bunch of info.
I got my laptop to recognize it, the usb connection is very touchy. Going to hook it back up to my rig and see if it works. Will report back shortly.
