If is any consolation, my new iMac also requires that I keep a USB mouse handy for the same reason. Curiously, the wireless keyboard is generally (but not always) recognized, but sometimes I have to borrow a USB keyboard to log in.
The spare mouse I keep is in fact part of a cheap Microsoft wireless kb/mouse combo that also works via a dongle, and which has literally never failed to start. I think the difference is that the dongle emulates a USB mouse and kb directly, but there's essentially no documentation for it so that's a guess.
(Before you ask: I prefer the feel of my BT mouse, especially for scrolling, which is why I don't use the MS one except when forced to).
