Limesdr mini ,usb does not recognize,what is the reason?

Hello everyone, my limesdr mini is broken, usb does not recognize, led light has been showing red, fpga firmware can be downloaded using JTAG, what is the reason?what should I do? thank you!

Hi haozi, I have the same problem with you. When I plug in my mini, then its led light becomes red, normally it should be red and yellow twinkle alternately. Do you know the solution now? Thanks!

If you are using windows, try it on windows 10. windows 7 doesn’t have the proper driver neither it allows to update. Then test if your board is okay with this test.

This will generate a report and you will be sure if your board is okay or not.
