A couple weeks back I ordered the SPRacing board from you and today I had some time to try it out.
I'm having trouble getting the USB to connect to the board. When I plug it in Windows tells me the device is not recognized / device malfunction. Also the red LED keeps blinking on the board. Previously have been using a naze board, not sure if the same drivers apply, so also tried installing the drivers SPracing recommends in the manual. In the device manager I see it connected under "other devices" as "STM32 virual com port" (with an exclamation point on it)
Any ideas what to do?
