Yesterday I purchased a Dynex USB to Serial adapter at Best Buy, one that is supposed to be Mac compatible. I installed the driver, obviously the device was recognized because it shows up in System Profiler, but lo and behold there is no serial port available to my Mac applications. No /dev/ttyUSB, nada. The cable is good; it works in Windows after driver installation, and it works under Arch Linux without any effort beyond plugging it in. The OS X drivers however, are apparently sub par (incompatible with Leopard?).

Anyhoo, I have VMWare fusion with an Arch Linux virtual machine running on my Mac, providing a shell to log into from an Apple IIe. And I plug the serial adapter into a Windows laptop to do ADTPro disk transfers. I would like to nix the Virtual Machine and the Windows laptop at some point, and do this all on my Mac. If anybody has some advice in that regard, shoot me an email. For those in the same boat, I feel your pain. I'll post a solution if I ever get one. 'Til then...

UPDATE: The Dynex USB to Serial adapter can be made to work with Leopard using this driver...
