How do I reset the MM8108-EKH19 EVK?

I bought 3 EKH19 EVKs (the little USB ones). Had them working in 802.11s. One of them stopped working for unknown reasons. I want to try resetting, but there is no reset switch. Can someone show me how to perform a hardware reset of this device?

Thanks in advance!

The button on the side is the reset button. See the user guide (section 2.3).

Found it thanks. Dummy me was looking for it on the USB dongle.
