great, thanks for the dump.

ok

i need at least one more extra hcidump to answer this question. the most 
likely answer is that winxp just ignores psm's that mouse advertises and 
uses default ones (0x11 - hid control and 0x13 - hid interrupt). you 
see, initially host and hid device do not know anything about each 
other. so the host must query hid device using sdp (Service Discovery 
Protocol) to find out all hid service parameters (such as psm's, hid 
descriptor etc.). any hid device must provide this information. that is 
what bthidcontrol(8) does - it queries hid devices using sdp and dumps 
all parameters so bthidd(8) can uses them.

> How to find what happens ?

to rule out bthidcontrol(8) i need hcidump while you are doing 'query' 
command.

- run 'hcidump -w bthidcontrol.dump' as root

- run 'bthidcontrol -a mouse query'

note: you may need to reset the mouse again in order for this to work.

thanks,
