I've been using pyserial quite successfully to control a USB-to-serial converter.

That is, controlling a couple of RS232 serial devices via the USB port through a KeySpan USB-to-Serial converter.

Pyserial seems to make communication through the USB port quite transparent, at least on my OS-X system.
