Comment 14 for bug 268502

The same problem for me with the final 8.10 intrepid ibex and a D-Link DBT-122.

Blink green power and link and nothing more...

lsusb:
Bus 006 Device 003: ID 2001:f111 D-Link Corp. [hex] DBT-122 Bluetooth adapter

lsmod | grep bt:
btusb 21912 3
bluetooth 70820 15 btusb,rfcomm,sco,bnep,l2cap
usbcore 175376 8 btusb,snd_usb_audio,uvcvideo,snd_usb_lib,usbhid,ehci_hcd,uhci_hcd

If I plus and unplus my key I have a normal dmesg like:
[ 851.624013] usb 5-1: new full speed USB device using uhci_hcd and address 3
[ 851.857750] usb 5-1: configuration #1 chosen from 1 choice
[ 923.456037] usb 5-1: USB disconnect, address 3

but the first time I plus and unplug, I have it:
[ 359.864020] usb 6-1: new full speed USB device using uhci_hcd and address 3
[ 360.060177] usb 6-1: configuration #1 chosen from 1 choice
