I recently got a pi, and I have been trying to use my usb keyboard and mouse, but I have a strange problem where any usb device plugged into the pi will spontaneously stop working between 30 seconds and 2 minutes after I plug it in. The devices are all rated under 500 ma and I am using an apple iPad charger rated 2.1 amps. Also I have an 8 gb sd card with raspbian. Please help :?

Same here. Have a 256MB pi that works great. Just got a 512MB one. Same exact hardware plugged in and it stops working. Will work for a time, but as soon as the processor gets a load it locks up.

Please make sure you are using the latest version of the distro. Also, you may need to force the device to use a particular USB speed - information on the Wiki about that I think - or there is the USB Redux thread here.

Well, I found a solution. My solution involves putting a fan over the pi to cool it off. Problem solved! :D

That would imply there is something wrong with the Raspi...it should never overheat in this way.

Does this suggest you are drawing too much current through it ?
