Hi all!

I bought a PS2 to USB adapter last week to connect my Desktop keyboard to laptop. When I connected my PS2 keyboard to laptop through adapter, it didn't work. I thought it must be the problem with adapter and removed it. But later when I connected the keyboard back to my Desktop (Ubuntu was running while I connected the keyboard), it is not getting detected at all! Now It is paining as I can't select and access other OS on my Desktop.There is no blinking of green lights or any other indication to know keyboard is supplied with power.

Is there any way to get my keyboard working again ? It is important because I tried two other keyboards(my friends') with the adapter and they are also not working now!
