[ 3.143609] usb 3-6.3: new full-speed USB device number 7 using xhci_hcd [ 3.225202] usb 3-6.3: New USB device found, idVendor=0a5c, idProduct=2148 [ 3.225847] usb 3-6.3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 [ 3.225848] usb 3-6.3: Product: BCM92046DG-CL1ROM [ 3.225849] usb 3-6.3: Manufacturer: Broadcom Corp [ 3.225850] usb 3-6.3: SerialNumber: 00198600002E Vinicius, I'm not so sure usb HCI firmware/adapter is the issue. There seems to be no record of the specific usb product id in btusb.c or btcm.c But some non-PatchRAM broadcom's can be updated according to a Mac OS PatchRAM program on github. Does this device need a firmware update? I got the *newish* Broadcom windows driver for an IOGEAR that seems to have the same USB ID's. Mine comes from the same factory as the ASUS one by the look of it without the ASUS logo, and ASUS has no drivers on their website https://www.asus.com/Networking/USBBT211_Mini_Bluetooth_Dongle/ https://www.iogear.com/support/dm/driver/GBU421 Kicked off the installer via wine (needs MFC42.DLL) to see what's inside and got some tips from here: https://www.tonymacx86.com/threads/brcmpatchram-upload-firmware-into-broadcom-bluetooth-usb-devices.150661/ %BRCM2046_UHE.DeviceDesc%=BRSMARTUSB, USB\VID_0A5C&PID_2148 BRCM2046_UHE.DeviceDesc="Broadcom 2046 Bluetooth 2.1 USB UHE Dongle" The latest drivers are here: https://www.asus.com/us/Motherboards/X99DELUXE/HelpDesk_Download/ - that didn't have by USB device ID in it. https://github.com/RehabMan/OS-X-BrcmPatchRAM Because this one does HID at boot, it doesn't RAM patch any firmware into the device, at least in the Windows XP driver. So I guess the problem is either with the chip (broadcomm - do you need to make a patch?) or it's SCO setup using the wrong packet types. I'll test my vanilla kernel and try and connect to an Iphone6 that should do eSCO EDR 3-EV3 packets tonight. I looked into this because udevadm monitor --property |grep FIRMWARE reported nothing. It's not using firmware.
