I *think* this is the same keyboard. Anyways IBM also has drivers for the keyboard, which they call Rapid Access Keyboard. Those drivers are newer. They have RAK, RAKII, and RAKIII drivers, and some seem specific to a certain IBM computer or two. I can't determine if the kb is RAK, RAKII, or RAKIII. (the IBM model no. isn't recognized by IBM's product search webpage and the kb isn't labeled) Anyways I'm fairly certain that RAKI isn't USB, the RAKII is USB but doesn't have any USB hub functionality, and RAKIII has a 2 port USB hub built in. I'm confused a little myself. I havn't tried the IBM driver yet, but I can say that the Micro Innovation driver does seem to have bugs on my computer (YMMV).
