I use a Kinesis Advantage USB keyboard with my Lenovo X230 laptop. It worked fine until yesterday when I updated my system. I have tested the keyboard with another laptop -- it works fine. I also tested another regular USB keyboard with this laptop -- and that works fine as well. It seems that the keyboard works immediately after I plug it in, and continues to work as long as I continue to hit keys. However, if I stop clicking for more then 5 secs, it stops working permanently.

I'm not sure what to do.

When I plug it in, I see the following in the system log:
Code:

Any help would be greatly appreciated.

look in your dmesg, if the keyboard stop working, you should have a disconnect message then (ps:watch -n1 tail /var/log/dmesg before you tell me you cannot type dmesg anymore)
