charset="UTF-8" For years I have been trying to get Bluetooth to work on my Lenovo T16 AlderLake laptop.It came with a AX201 WiFi/Bluetooth interface and I was pleased when iBluetooth was supported, but didn't work, so I spent $7 on a CRS5810 which is claimed to work well on FreeBSD. Unfortunately, I still see the same problem so I now assume that the problem is me. When I insert the CSR I get: ubt1: on usbus1 This is almost exactly what I see at boot on the AX201. According to Handbook, I should see something like this: ubt0: vendor 0x0a12 product 0x0001, rev 1.10/5.25, addr 2 ubt0: Interface 0 endpoints: interrupt=0x81, bulk-in=0x82, bulk-out=0x2 ubt0: Interface 1 (alt.config 5) endpoints: isoc-in=0x83, isoc-out=0x3, wMaxPacketSize=49, nframes=6, buffer size=294 usbconfig shows: ugen1.4: at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON (100mA) I tried starting it, but it fails with /etc/rc.d/bluetooth: ERROR: Unable to setup Bluetooth stack for device ubt1 Can anyone suggest what probably obvious thing I might be missing?
