USB Port stops working after few minutes of startup

I've recently purchased a toshiba portege r835 and for the last couple days I've been having problems with one of my USB ports. Right after I startup my computer, it works fine for a few minutes but then it stops working completely until I restart it or put it to sleep and wake up computer. Can anybody help me with this? My guess is that the port is going to sleep to save power. In an attempt to fix this, I went to the device manager and cleared the "allow the computer to turn off this device to save power" box for USB root hub(there's 2 of them on the list) and also the generic USB hub(also 2 of them) It's still not working so I was hoping for some help.

Clarification Request
2 ideas.

1. Do nothing. It's recently purchased so call it in and let them fix it.
2. Use system restore to when it worked.

ehh i suppose i could but then i'd have no laptop for a while as they fix it and with the restore, i'd have to reinstall a lot of things and move a lot of files. I'm not saying that's not an option because I will restore it if i have to but if there's a solution that doesn't require that, I'd be much happier.

Idea 2 does not involve such losses.

I think you may have thought I was thinking about System Recovery but I wasn't.
