[En-Nut-Discussion] USB SAM-BA CDC Driver

[Ulrich Prinz]

Hi!

The flash loader software is from ATMEL. The CDC profile is a simple
UART profile that treats a USB device as a local serial port. The CDC
profile is specified in the USB protocol by the USB members.
Any normal PC OS brings such a driver but with Vista Microsoft simply
forgot to add it. There was a service pack to Vista that adds it in.

With Windows 7 there where again troubles... I never left Windows XP and
will switch to Linux completely with my next PC. But colleagues are
having troubles by using USB tools that worked fine under XP.

If there is a CDC driver added with the Samba tool is may be added by
Atmel for you convenience but I doubt it is a special one.
