The usual USB issue with Windows is a driver one. I've run into this hundreds of times now. But I can't comment much here since machine details are missing.
If it's like all the others, motherboard drivers usually fix this.
Hi I recently purchased a 5G video ipod and tried to use it on my windows xp machine using a firewire cable that came with my older 3G ipod. Windows XP did not recognise the ipod and suggested that I plug it in using a usb cable. Does any one know of a fix or patch I can use to get windows to recognise my ipod when plugged in using firewire cables?
