Hi! I have problems with getting a Trust 5.0 usb bluetooth to work properly with my raspberry pi 5. Most of the time when I boot the rpi I see "RTL: download fw command failed (-110)" in dmesg log. I can get it to work if I unplug/replug it several times until fw download succeeds. I dont know if this is a kernel-usb/firmware issue on rpi5? When using fedora 40 on my laptop I have no issues
I have disabled to internal bluetooth adapter in /boot/firmware/config.txt
dmesg log:
