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. In case any further information is required to investigate this, feel free to contact me. P.S.: For details on how to get bluetooth working with this chipset, see also this thread: https://github.com/winterheart/broadcom-bt-firmware/issues/3 as well as the linux wireless page on the wifi 802.11 part of the same device (the NVRAM part is also required for blueetooth): https://wireless.wiki.kernel.org/en/users/drivers/brcm80211#nvram_from_efi -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
