Hi Fred, > I have a Wortmann / Terra mobile 360-11 netbook with a Broadcom bluetooth/wifi chipset BCM4356A2, running Debian 10 buster (testing), linux kernel 4.11.0: >> $ lspci -nnn | grep Broadcom >> 02:00.0 Network controller [0280]: Broadcom Limited BCM4356 802.11ac Wireless Network Adapter [14e4:43ec] (rev 02) > > When loading the appropriate kernel module, it complains about a missing firmware file called "BCM4354A2-13d3-3485.hcd" (note the 4354 instead of 4356!): >> bluetooth hci0: Direct firmware load for brcm/BCM4354A2-13d3-3485.hcd failed with error -2 > To my knowledge, a file called "BCM4354A2-13d3-3485.hcd" does not exist. > > The solution for me was to use (=rename) the file "BCM4356A2-13d3-3485.hcd" instead (note the 4356 vs. 4354!), which actually matches the device name as reported by lspci. > > Could this be a typo in the kernel sources, requesting the wrong firmware file? > Please check/correct if necessary. Broadcom is not releasing any firmware files. So they are no official names. Can you send the resulting binary trace.log from “btmon -w trace.log” around so I can see what kind of hardware is this and what it does. Start btmon before attaching the USB dongle or loading btusb.ko.
