I can't vouch for these new drivers, because my older Si Labs USB drivers for Mac work just fine with SL.
IF you are having problems with iBike Mac software connecting to your USB adapter, and IF your problems are related to Snow Leopard, then try installing the new USB drivers attached to this post.
After unzipping the drivers install them in the usual way, then restart your Mac.
NOTE: IF YOUR USB ADAPTER IS WORKING WITH YOUR MAC, THEN DON'T INSTALL THESE DRIVERS: WHY MESS WITH SUCCESS?
