Hi

I've been having fun with bluetooth in .38-rc. My adapter was old (bt 1.1) and the bluetooth stack was having 'fun' with it.
Got tired of that a got asus doggle that supports 2.1+EDR. Then I tried to use my magic mouse. It works for a few
minutes and then stalls. The stalls seem to be related to touches. If I am careful only to touch with one finger it
seems to work. It usually works with two fingers, with three it stalls. Running hcidump sometimes lists a last
packet with a dlen of 35 when it stalls. Powering it on an off reset things

> ACL data: handle 21 flags 0x02 dlen 27
L2CAP(d): cid 0x0041 len 23 [psm 0]
> ACL data: handle 21 flags 0x02 dlen 27
L2CAP(d): cid 0x0041 len 23 [psm 0]
> ACL data: handle 21 flags 0x02 dlen 27
L2CAP(d): cid 0x0041 len 23 [psm 0]
> ACL data: handle 21 flags 0x02 dlen 35
L2CAP(d): cid 0x0041 len 31 [psm 0]

This was not a problem pre .38. It started happening in .38-rc along with other bluetooth problems. I figured the bt
problem was the root cause - I was wrong.

This ring any bells?

TIA
