1st Gen Nano not recognizing power

Hi everyone, I'm new to the forums. Recently, I got an iPod Touch, and I wanted to import all the songs from my 1st gen nano onto it. Since some of the songs that were on the nano had been lost, I had to copy album artwork and album titles onto iTunes. Anyway, I was using a USB 1.1 cable. It gave me a warning sign, saying that there was not enough power to run the unit. That made sense, so I went out and bought a 2.0 cable. When I plugged it in, the same message appeared, despite it being the faster connection. I can now no longer plug in my nano, and cannot transfer or copy any files. Any help would be appreciated. Thank you.
