Hello,

The regression persists even in the latest kernels.

Decided to collect some more debug information on this problem. This
output is from the same system detailed above running on
kernel 2.6.28.10:

Here is the output of hciconfig -a:

Since you mentioned that you suspect that this is a USB problem,
attached is the usbmon capture of trying to l2ping the phone
(usbmon_l2ping_bt_dongle.txt). Also attached are the contents of
/proc/bus/usb/devices at the time of testing (devices.txt).

Finally, I note that my problem seems to be identical to the one described in:

http://bbs.archlinux.org/viewtopic.php?id=60158

The user there also notes that this is a regression introduces in
2.6.27, which is also my experience.

I hope this helps. Much obliged.
