I purchased a PRS-600 for my galfriend.
When if arrived, I connected it to my PC to look it over.
All seemed to be just fine with it.
So, I took it over to her place to give it to her.

When I hooked it up to her PC it was not recognized.
I spent the whole weekend fighting it trying to get it to work.
The situation just got worse.
I finally gave up and brought it back home with me, expecting that I'd have to do a warranty thing with it.
Lo and behold, it works just fine and is still recognized by my PC, all the software installs properly, etc.
Luckily I didn't break it while wrestling with it trying to get it to work on her's.

Now that I'm looking back at what happened, it seems that something is wrong with the USB on her's.
I did seem to get worse as I fought with it for 2 days.
Finally, I couldn't even get it to charge by USB.
But, the screen did show that it was hooked up to USB.
Now, it is hers not mine.
I need to get it to work on her PC.

Anyone have any idea as to how to proceed with this?

Again, the problem is not the reader.
It appears to be her PC.
