Comment 26 for bug 39414

I have the same problem with my "Blue Soleil" Bluetooth dongle (Vendor:Device = 0e5e:6622). I've found you can suppress generation of the messages by changing the "isoc" parameter passed to the "hci_usb" kernel module. Depending on distro, you might put "hci_usb isoc=<new value>" in '/etc/modules' or "options hci_usb isoc=<new value>". For me, "isoc=3" causes "connection handle 92" errors. This method can only be considered a workaround, as non-optimal "isoc" values may have undesirable effects on hardware. I think the problem would be best cured by the designers of the "hci_usb" module consigning the detection of "connection handle" errors to the debug mode of that module.

On my system, "modinfo hci_usb" shows, in the "description" field, that I am using "Bluetooth HCI USB driver ver 2.9". It is THIS version, not the kernel version that is important in this "bug", as "hci_usb" is spewing out messages to the syslog. Just for the record, my kernel version is 2.6.16.13
