Hey everyone, Linux v5.10 broke firmware loading for my AR3011 Bluetooth USB adapter. A git bisect identified the following commit as the culprit: > commit b40f58b973865ee98ead884d2bdc7880b896ddb8 > Author: Rocky Liao <rjliao@xxxxxxxxxxxxxx> > Date: Tue Sep 29 12:23:51 2020 +0800 > > Bluetooth: btusb: Add Qualcomm Bluetooth SoC WCN6855 support > > This patch add support for WCN6855 i.e. patch and nvm download > support. The accompanying patch describes the issue further and attempts to offer a fix based on my superficial understanding, which may or may not be adequate. Regards, Florian
