Posted on May 17, 2011 at 13:03USB is not ''Host-OS'' dependant.
Since USB is device-only across all of the STM-32 line, you have to connect the device to a Host, like a computer.
Now, USB is universal. You can use it for almost anything involving moving bits around. The host's OS will communicate with a STM32, and will need driver to fit your code.
Example, if you code a ''virtual com port over USB'' (As the FWLib included example), XP/Vista/Linux/MacOS all includes a driver to properly communicate to the device ''class''.
If your code a USB Audio device, then again, there is a standart that can be followed for Windows to use it's own embedded drivers.
If your code is something damn weird for a very novel communication need, then you will have to WRITE YOUR OWN DRIVER, on any OS you prefer!
That is the cause most computer peripheral manufacturer does not provide drivers for all OS under the sun, as each requires their own rewrite of some sort of driver.
Hope that helps,
