From the day 1 with my punto, I have been using the USB port to charge the camera, mobile phones, Ipod and what not. I havent faced any issues. Touch Wood. Now I was thinking of getting a Belkin USB Hub to connect it to BnM always so that I need not remove the Songs Pendrive to charge the camera or mobile. Now after reading all these stories, I think I should drop that idea of a USb HUB.
