I have heard that not all generic USB chargers work on iPods - maybe the one you bought is not compatible with iPods.
If what you have is the original Apple power supply (the square white one with detachable plug and Apple logos on both sides) yet still doesn't charge your iPod shuffle, it's probably broken.
Purchased a generic USB charger today. After connection LED light on ipod flashed thrice (orange) and then LED switched off automatically. Tested the voltage out put through dock pins and compared with another mains charger (Apple certified) which works. Voltage at the two data pins (Top 2) showed +3 V in the charger(that works) but 0 V on the chager which did not work. The other two pin (bottom +ve, next -ve) showed +5 V and 0V respectively on both the charger. My conclusion is that the data pin connections for shuffle might be different for some reason. Any body knows anything about it. In Google I fount one picture which showed that there is a circuit board within the dock. The Dock for Shuffle 2nd Gen is not just a USB to 3.5mm connector.
