Problem with arduino Uno finding a com port.

-

i have nasty problem arduino uno finding com port.
i have started use arduino in secondary school classes since september.
we use 8 laptops, (xp, vista , seven) arduino uno's. use ardx experimentation kit. sketch cannot uploaded ('problem uploading board') because there no com port available. searched forum, not find real solution. works (after pulling out usb cable, changing other usb port, restarting arduino ide, restarting laptop etc.) frustrating , time consuming me , students.
does have solution this?

the uno has own unique serial drivers have loaded on pc. below may have more useful info.
