I have a 4g 40gig grayscale ipod that I've just installed rockbox on. First of all, thanks to the developers for a great product. I've looked at the forums, the manual, and the wiki for solutions to my problem, and have tried a variety of things, so I'm hoping there's something else I can try. I have both USB and Firewire cables/wall adapters, and charging works fine with Firewire whether I use a wall adapter or a computer. USB works fine with the computer. However, I can't seem to get the USB to work with the wall adapter. I have tried holding menu from within rockbox while plugging the cable in, as I've read about in the forums and faq, to get charging working. I've also tried rebooting into the Apple firmware before plugging in, and neither seems to work. Is there anything else I might be able to try?
