The way the promises are chained in the demo app it is impossible to tell which method is triggering the error. I assume you have modified the code in some way to distinguish. It is easy to get this wrong and end up catching errors you don't expect. My guess is that on your device the interface number is different. Can you confirm by looking at the USBDevice object that it has an interface number 2?

It was actually in the controlTransferOut function. I had changed the interface number in all the other places except for the one inside the control transfer. Thanks for the great example project!
