Presently have both wireless USB keyboard and mouse working under Linux (Debian v3.0 unstable, Kernel v2.4.25). Automatically recognized and enabled at bootup with Gnome v2.4. Requires kernel modules usbcore, usbmouse, usbkbd, and hid, although one these occasionally causes a kernel segfault at bootup (doesn't crash PC; wireless keyboard & mouse simply don't work). No word yet whether the keyboard's "secure" mode is supported, which could be a serious password security issue given that I've tested the keyboard from at least 10feet from its receiver.
