Hi all,

I have built AVR Doper, windows see it as COMx in CDC mode but in AVR Studio 4 it constantly says Detecting....FAILED!

Can anyone tell me what can be wrong??

Thanks!

Can you try avrdude in verbose mode? It might give more information about what's going wrong.

There is a known problem with CDC mode on some machines. If there are communication errors, Windows may stall the endpoint and thus stop polling the device.
