My mobile phone showed up as present on one of the release candidate kernels, so mine is not fake. We could always borrow a friends laptop that runs Micros~1youknowwhat and test the dongles for operation.
I am not saying that my dongle does not work at all. What I am saying is that my dongle claims to be based on a CSR chip although it is not. The USB IDs corresponds to CSR but the chip label says ASC AS3620QA. This is a counterfeit.
Is very easy to tell. Just open your dongle and check the label on the chip. Best regards, Alex
