There is a Pocket Wizard Utility available for download that will allow you to download firmware updates for the USB version of the MultiMax and the newer TT1 and TT5 units. The software also lets you configure the TT1 and TT5 units.

There doesn't seem to be any firmware updates availabe yet for the MM units at this time, though.
