I have been using OpenIMU 3ooZA EVK under Windows 10 for a while. it all works fine until recently. After a reboot of the device the Windows Server 1.1.1 just keep Testing ports ...

I checked the port (in this case COM 7 ) by HTerm, it shows >> Erro in Open Port: COM 7 blocked by another application

Well, I tried to search all process that may occupy the port, Nothing found!
also tried to reboot PC, change USB port, Unplug all other usb devices, replug etc. NO Luck.

I somehow ran out of idea. Strange thing is it worked just fine before the reboot of EVK. Any advice would be much appreciated!!
