Open a terminal and try: lspci
(presumably with a wired keyboard and mouse)
If you boot with the bluetooth HIDs active - swap to wired HIDs, then look at dmesg for references to the wireless ones.
Wireless HIDs are not normally a problem, since they look just like the normal version as far as the OS is concerned. However, these are bluetooth devices. I don't think bluetooth support is included with the live CD right now (someone correct me) - though you will definitely get it in the HD install.
Here's some wireless in ubuntu guides:

While I see a lot of references to wireless/bluetooth working out of the box with edgy, it is never clear that this is the HD install or the desktop running live.
