Hmm yeah, this dongle has no usb hid part. So this driver will not work with this dongle for sure. I already have an idea how to support all 3 series, though it involves a lot of testing. I would provide a github repo with tools and test kernel modules if you are interested. But I don't know yet how long it will take, I work on other stuff which has a higher prio. greetings, Wilken > -- > > Thomas > >
