You certainly can use the usb cord provided for charging (remove it from the provided electrical plugin cartridge so that it will then plug into your pc).
I used that for a few days, but then I went to Fry's electronics and bought a "Retrak" retractable usb cord (which has the same fittings on each end as the cord provided). I have used retractables previously for other uses but was never satisfied, because after a few uses they don't retract completely. But, this "Retrak" cable is amazing. It goes right back snugly when not being used and there it just dangles on the side of my laptop without getting in the way when I put it in my briefcase or use the computer not connected. I have used it for over a month and it still functions perfectly.
When I connect with Pdanet, I pull it out the (very thin) retractable cord and I can even have my phone in my pocket. And, by the way, Pdanet is an amazing tether app (works perfectly without having to have your phone rooted). Another nice benefit is that your phone is charging while you are connected and tethering and surprisingly you can get a phone call without having to disconnect, and after the call is complete the internet cruising continues uninterrupted.
