Dear Linux folks,
To debug the issue with file transfers to the Nokia N9 [1], I would like
to pass through the USB Bluetooth wireless to QEMU.
$ lsusb
Bus 001 Device 004: ID 1bcf:28ae Sunplus Innovation Technology Inc.
Laptop Integrated Webcam HD
Bus 001 Device 003: ID 8087:0a2a Intel Corp. Bluetooth wireless
interface
Bus 001 Device 002: ID 8087:8001 Intel Corp. Integrated Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
$ ls -ld /dev/bus/usb/001/003
crw-rw-rw- 1 root root 189, 2 13. Jan 23:05 /dev/bus/usb/001/003
Then following Leif’s article *QEMU USB host device pass-through* [1], I run
$ qemu-system-x86_64 -version
QEMU emulator version 6.2.0 (Debian 1:6.2+dfsg-1)
Copyright (c) 2003-2021 Fabrice Bellard and the QEMU Project developers
$ sudo qemu-system-x86_64 -cpu host -m 2G -enable-kvm -usb -device
usb-host,vendorid=0x8087,productid=0x0a2a -hda /dev/shm/debian-64.img
-net nic -net user,hostfwd=tcp::22223-:22
(`-device usb-host,hostbus=1,hostport=3` did *not* work for me.)
In QEMU with *linux-image-5.15.0-2-amd64* 5.15.5-2 and *bluez* 5.62-2
the device is now detected, but bluetoothctl does not detect the
controller. (Starting QEMU as root does not make a difference.)

Do you have an idea, how to get it working?
Kind regards,
Paul
