The -V helps a lot.  I have attached a short hcidump listing from when I power
on the headset and it attempts to make a connection and fails.

Yes.  I was able to do the following:

hcitool cc bdaddr
hcitool dc bdaddr
hcitool cc bdaddr
hcitool info bdaddr

And it is working just fine.  It only seems to misbehave when I power it off.
Are any other people on this list using a Plantronics M2500 headset and, if
so, are you experiencing anything similar?
