I am having the similar symptoms as a previous post, pointing to the fact that it may be a hardware issue:
I’m running win 7 64 bit. Funny thing is, it was working fine for about the first hour, and then went on the blink. as of now, I cannot get it to work at all even for a few seconds. I suppose it might after a reboot, but that is not a lng term fix.
It is on a Lenovo ThinkPad X201 with a docking station. I just tried plugging it straight into the laptop too, nothing.
Now that it is several months later, should I try a differnt driver then the one suggested to the previous person? (i’m using whatever the latest one is as of today) Should I try something else? Shoulod I send in my amazon #?
