I just cloned my Windows 7 hard drive to a new SSD.

The system will boot from it, and when it does the USB mouse works, but the USB keyboard does not. It's plugged into a USB 2.0 port, and it does work fine to invoke the BIOS setup, but not once Windows starts. The keyboard works fine if I boot from the old hard drive.

Any ideas?

How long did you let it sit to allow Windows to (re)detect the keyboard? It can take a minute or more the first time (sometimes). Have you tried moving KB to another USB port? – Ƭᴇcʜιᴇ007 Feb 9 '13 at 15:05
Quite some time. My userid requires a password, and I can't enter it. And yes, I tried the keyboard on several different ports. – user196968 Feb 9 '13 at 15:15

I just recently had this same problem. The odd thing was that another identical keyboard was recognized. I followed this tutorial on to reset the USB drivers and it worked. Basically, you have to remove all the drivers for non-present USB devices and then when you plug them back in, Windows 7 will re-install the drivers. I also removed the drivers in the Human Interface Devices and Keyboards categories rather than just in the Universal Serial Bus controllers category.

Thank you - that was a great suggestion, and I learned things by going through the process, but it didn't solve the problem. – user196968 Feb 9 '13 at 16:38
It does say that you may need to go through it multiple times to get it to work. YMMV – ChrisN Feb 9 '13 at 16:50
