I'm using FreeBSD 14.0-RC2
When I insert a FreeBSD compatible Bluetooth dongle (CSR 8510) to USB 3.0 port
on my front panel everything works fine. But when I plug in the same dongle to
a USB 2.0 port on the front panel I get this output:

This output continues non-stop until I reboot my computer. 
Bluetooth won't work. It gets very slow and I can only transfer very small
files between my Android phone and my computer. If I try to transfer a file
about 2mb in size the transfer stops part of the way through. Also transfer
speed is very slow.
This output continues non-stop until I reboot my computer. 
If I plug in a data USB stick into the same front panel USB 2.0 port everything
works fine. 
If I plug the Bluetooth dongle into a rear USB 2.0 port everything works fine.
I only get this problem with Bluetooth using the motherboard USB 2.0 header.
I tried using an AX200 card with integrated Bluetooth with a PCI-E adapter with
a cable connected to a spare USB 2.0 connector on my motherboard.
iwmbt-firmware installed fine.  AX200 wireless works but I get the same error
messages as above maybe because I'm using the USB 2.0 header on the
motherboard?
I have a laptop with AX200 and Bluetooth using FreeBSD 13.2 STABLE and
Bluetooth works fine. 
So if I try to use Bluetooth with internal USB 2.0 either through front panel
USB port or through PCI-E adapter card I get errors. Using USB 3.0 or other USB
2.0 ports I have no trouble.
Am I missing something?
