I have a problem on my c4 picasso that sometimes when I plug in a USB device it sometimes comes up with a fault (USB device not available. Power supply fault. Please disconnect all devices) no matter how many times I disconnect and reconnect the fault remains. Other times when I go to get in the car it works fine. Anybody else experienced this before? Also is it possible to add a photo of the fault?
Thanks.

Is this a USB stick that you are inserting or is it a device connected by a USB lead.
If it's a lead connection have you tried a new lead. Possible you have a wire dry jointed or broken in the lead.
Also is it always with the same lead. Some leads are just charger leads some are charger and data.

Hi Stimulator, thanks again for the reply. It's when connecting a phone via a cable, tried different cables but still the same. Really random as well. Sometimes works fine, other times comes up with the fault.

What happens if you wiggle the connector at the phone..

Nothing, just the same.
