It's certainly a solution for me as I said to Daniel. I can't explain why but it's definitely connecting at High Speed now as mp3 transfer from Amarok is very fast now. The front USB ports connect via cables to the motherboard. My motherboard I don't mind sharing with you is http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ClassValue=Motherboard&ProductID=2507&ProductName=GA-M61SME-S2
The specs seem to indicate that all the usb ports front and rear are 2.0/1.1 speed. The only things that I can think of is the cables supplied with the rather cheap case to connect the front usb ports to the mb are sub standard and this is causing the fussy ipod to not getting exactly the right voltage. :)
