usb devices on windows 7

[lifej]

these devices never came with any documentation so I don't really know what is what. Some of it is displaylink, some of it is vi-book. I bought these maybe 4 years ago. I have been using them successfully on my xp computer. now I just got a new W7 computer. It has a nvidia graphics card GT530.

When I put on the software that I had i got it all to work to where the mouse moved, and i could even drag windows around, but they would remain inaccessible.

Now, I'm not real computer knowledgeable, so first I guess I need to even identify what is what - whats the device called, which version number?

then my two pieces of software - one is the driver dor the usb device - that's probably the displaylink part? what's that driver likely to be called, so I can identify what I have.
the other is some extra desktop managing software , i guess - that is probably from villagetronic?

and then I need to make sure i have the latest software and driver, and for that matter, that these devices WILL work on a W7 64 bit computer

Sorry I don't understand how to navigate this forum, I hope I can even figure out how to look up responses, but perhaps someone would be kind enough to send an e-mail to lifej@mcn.org that they have responded
