If you search on say aliexpress (*) for > csr8510 then you will find several dongles which are advertised as "origi= nal > csr8510 chip" in my experience these indeed contain a real CSR8510 chip a= nd > they work a lot better then the clones. So the best advice which I have is > just to order one of those. Is there a way the kernel could identify those as a fake/clone, and adverti= se this in dmesg? It would make debugging user reports much easier as we could just say "get an original instead of a fake/clone". This chipset (and clones) seems to be very common, almost any USB dongle I = can find has this chipset (or a clone) inside (according to lsusb), and some wo= rk, others don't. This chip is even in dongles of manufactures who somewhat cla= im that the Bluetooth dongle is completely made by themselves (with no mention= of the CSR chip inside), or maybe these are just fake dongles with a brand nam= e on it, I'm not sure. It's difficult to get something else even if you're not looking explicitly for CSR. --=20 You may reply to this email to add a comment.
