USB Haptic device (req for comments)

[andrey_utkin]

Hi!
I am seeking for a solution to have haptic notifications on desktop/laptop workstations. I.e. to pass vibration to the workdesk.
One possibility is programming a smartphone... But what feels more right is to make a dedicated USB device!

While thinking on it, I've met this article: http://spectrum.ieee.org/geek-life/hands-on/diy-musclememory-programmer

It feels very close to what I want, I just want even simpler thing - to control one motor! So I would appreciate even simpler design. Like, USB -> microcontroller -> motor. I wonder if there is any microcontroller/SoM which would connect directly via USB (without need for separate UART piece) and which would allow passing enough current through its pins, to avoid separate power relay element.

It is not necessary for controller to be Arduino, I'm hardcore C coder and I believe I'll cope with some direct programming.

So compactness and simplicity is paramount for me.

Any suggestions for hardware to use?

Thanks for any comment.
