I just hooked up a new Midisport 4x4 USB to my Quicksilver G4. I installed all the most recent drivers for OSX 10.2 (m-audio usb midi 3.1)
and restarted. It isn't recognized in the audio midi set-up utility....no devices show up at all. In the system profile, it shows a device hooked up to the usb port I'm useing for it. None of the lights on the Midisport are lit though. Has anyone here had the same problems??

I'm suprised that you were able to find the drivers for OSX!
Now then, what version of OMS are you using? Gotta get that going, or it won't work.

When I unpacked the midisport there was a driver cd with all the different midiman and m-audio device drivers for OS9 and X. OMS 2.3.8 was also included. thats the one I installed. At the m-audio website they have a download option window that allows you to pick the device you're useing, the os version you're useing, And the current driver pops up for your download. The USB midi OSX 3.1 driver is the release version for Jag........Its not working for me though. The drivers for the Delta66 card works in both 9 and X
