[G4] Patch for Apple USB modem?

[John Erdman]

My G4 Sawtooth's internal modem bit the dust several years ago. I  
replaced it with the Griffin serial port. Since then I've been using  
a SupraExpress USB modem instead. Unfortunately that too bit the  
dust. When I couldn't find an identical replacement, I purchased the  
Apple USB modem without noticing the OS requirement of OS 10.4.3.

The OS on the Sawtooth is OS 10.3.2.  And of course the new modem  
doesn't work. Has anyone seen a patch that would enable me to use  
this modem without purchasing a whole new OS? (My current version of  
Tiger is a single user copy that came with my iMac G5.)

(And yes Phil.. I have searched the net and the Apple support site  
already... but no joy)

Thanks,
John
