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 220.127.116.11
