It's the same situation with USB Bluetooth dongles - many purport to be based on a Cambridge Silicon Radio (CSR - now owned by Qualcomm) chip, but are in fact using one of several cheap alternatives. Many of these clones have their own quirks, and the amount of work-arounding that's been added to the Linux drivers is quite notable. Kernel 8.5 onwards seems to incorporate most of the fixes, but along the way, patches like this were available: https://gist.github.com/nevack/6b36b82d715dc025163d9e9124840... Despite the fantastic efforts of the driver maintainers, I still managed to find a "CSR 4" cheap dongle that threw all sorts of errors in the logs and didn't work. I'm waiting for some Broadcomm chip-based replacements to arrive. |
