Hey everyone ill start by saying im not very smart with computers i have a pc with windows xp home edition with (4) user accounts set  up  I  was wondering if there is a way to dedicate (1) usb port that would only function with only the administrator account and not with the limited accounts or if i could get a program that normally "AUTORUNS" at startup to only do so with the administrator account and not the limited accounts. if your wondering I got "magicjack" PHONE service on a 30day free trail it works great if only on user at a time is logged on but if more than one at a time is logged in and the program runs with 2 or more users logged  in at a time its like if conflicts itself                     any answers would be appericated
Hello Kubota,

I don't think it would be easy to set something up like that. Their maybe some software but at a price. It MAY be cheaper and more feasible to do what I setup for my mother. (She ALSO has magic jack) I found a Pentium3 computer in the trash and USED that computer as a dedicated computer for the Magic Jack. Then I backfeed the VoIP so all of her phone jacks in her house worked.

Good luck on the software search.

Regards,
This can be done by setting up a new Hardware Profile and removing the USB ports and hubs in Control Panel.
Then use the Group Policy editor to make that the only profile they are able to log in to...
