PRS-300 Device not recognized

[Traclo]

Hello!
I am hoping someone can help me try and fix this (it is disappointing to spend so much then have it not work).

Here's the problem.
I am using Win7 x64, PRS-300
At first I tried to get the eBook Library program working. I installed it and tried to run it. Didn't work. Luckily someone on these boards suggested to just run it in compatibility mode.
It now runs fine. I can connect to the store and my computer is registered.
The problem is that when I connect the reader the eBook Library simply doesn't register that it is there. All that happens is windows pops up 'USB Device Not Recognized'.

Any suggestions?
What I've tried:
-Reinstalling the software
-Restarting my computer
-Restarting my reader
-Clearing the memory of my reader
-Running both XP and Vista compatibility mode on the software

Please help!

Wow.
Solved.

If anyone else has this problem... try using a different USB cable than the one provided.
I tried this 2 minutes after posting (look at the post times!) and it worked.
So if all else fails, try some other cable.

Needless to say now I'm excited!!!
