One by one by iPhone refused to charge from each USB port after a few goes, so I just moved in to the next one thinking it was a SW screw up. Now I can't power anything power hungry, eg USB HDD, from any of the USB ports - seems like they are all fried for high current loads.
Anyone seen anything similar?
NB It's a Toshiba Satellite laptop - sadly just outside the 2 year warranty from John Lewis.
