USB and LAN ports not working

I received my Raspberry Pi today, but unfortunately neither the USB ports or the LAN port appear to be working.

I have tried numerous low power USB devices like keyboards mice etc. but can't get any life out of them, although I am able to charge my phone from the ports. Same results using two different 2A adapters to power the Pi and with a powered USB hub.Tried connecting the LAN port but the light on the router indicating a device is attached did not come on.

I've tried Debian, Arch and Fedora from RaspberrPi.org and also tried the kernel update which I believe is to address a different issue with USB. At this stage I'm fairly sure there is a fault (LAN is connected through USB I believe?). I'll wait and see if anyone else reports similar problems, otherwise I think I'll have to return it.

Does anyone have any suggestions or has had a similar experience with theirs?

Thanks

There's a good Troubleshooting section at http://www.raspberrypi.org/forum/troubleshooting. Scan the topic list and see what's similar to your problem. From what I've read at the Troubleshooting section, I'd say the most likely culprit is a micro USB cable that's not able to provide enough current. Some micro USB cables have very thin conductors and the voltage drop can be enough to keep RasPi from working properly. The easiest way to check this is with a voltmeter (multimeter).
