one of the problems is data will have collisions going from a high speed device to a slower one, If you hook up a RS 422 device to a RS 232 port the 232 can't keep up with the RS 422 device so it won't work.

Check the dipswitches on the rear of the thing. The PC and Mac comm settings are different. I THINK that's the only real difference between the two (besides the label.) My 56k isn't here right now, but if someone else could post the dipswitch settings from the back of their working USR, that should do it.
Probably. ;-)

I have an external USR 33.6 voice modem that will not work properly with a Mac. I got it to dial but no matter what cable I tried or software settings, once it dialed through to the ISP, no more data was allowed to pass in either direction.
I have a much newer USR 56k voice modem with both serial and USB connections. Currently it's running on the serial port on my PC, had to update the firmware to make it Win 2K/XP compatable. USR says it will not work with a Mac and it probalby won't due to something USR has planted in the firmware to stop it from doing so. I dunno how they do it, but USR has made several external modems that are NOT software driven and require nothing but an INF file for Windows (or just an init string for Linux etc) that will not work with a Mac. Usually they had an equivalent Macintosh version of the same modem for a much higher price. Even nastier is some of those "Mac only" modems work fine with a PC.
