The solution is to move the BCM4324B.hcd file up 1 folder from /lib/firmware/brcm/ to /lib/firmware/ I don't understand why that would matter, so YMMV. The btattach still won't return, but the BD Address from hciconfig is real and it is possible to pair bt devices. I haven't figured out how to make the btattach auto connect at boot time, for me it is still manual after each boot. Like other T100CHI users, I need the device ID patched to include BCM2E71. Debian kernels seem to use ttyS4, ARCH derivatives use ttyS1. -- You are receiving this mail because: You are the assignee for the bug.
