Whatever you want, that was just a suggestion.
Where did you order from?
To anyone who is on debian and recieving kenel panics from their USB keyboard.
There is a hardware USB controller issue when running a high speed and low speed device at the same time. The USB ethernet counts as a high speed device, keyboard counts as a low speed device. The USB controller returns the wrong OP codes and Debian does not like this, other forms of linux will just have USB issues when plugging in stuff while having the USB ethernet enabled.
Disabling the USB ethernet in an OS will cause the USB controller to turn off the electrical connections to the ethernet, thus allowing you to have a low speed device. HOWEVER plugging in a keyboard and a USB hard drive which does not switch to low speed will cause the operating system to play up or fail.
Out of the 3 pi's I have tested, each of them have the same issue. And there are a large number of people complaining about certain USB devices not being recognised on the forum. They just havent worked this out yet.
This was worked out by borrowing a BT engineers oscilloscope and he JTag'd his PI as we investigated. This is how we confirmed/discovered the USB controller was returning the wrong op code.
