Hi Rocky, I'm writing to inform you of a problem with a change related to a commit of yours from 29-09-2020 to drivers/bluetooth/btusb.c. It seems that you removed one important check that breaks many bluetooth usb atheros devices, specifically this line, - /* Don't care about high ROM versions */ - if (ver_rom & ~0xffffU) - return 0; The issue is discussed here, https://bugzilla.kernel.org/show_bug.cgi?id=210681 The commit log here, https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/bluetooth/btusb.c?h=v5.10&id=b40f58b973865ee98ead884d2bdc7880b896ddb8 I can confirm that adding that check back fixes the problem for my bluetooth adaptor. Regards, steeve -- :wq
