Problem with Logitech Mx900 again

> dump with last attempt with pin-code in attachment.

thanks. in the dump you have provided i can see that bthidd(8) have 
successfully established l2cap connection on psm 17 (0x11 - HID control 
channel)

1119333385.368311 < L2CAP(s): Connect req: psm 17 scid 0x0042

1119333385.549241 < L2CAP(s): Config rsp: scid 0x0042 flags 0x0000

however, it could not establish HID interrupt channel on psm 19 (0x13 - 
HID interrupt). instead bthidd(8) tried to connect on psm 25 (0x19)! and 
of course mouse rejects the connection.

i remember you had similar problem before due to incorrect 
"interrupt_psm" value in the bthidd.conf file. in your first email you 
have posted your bthidd.conf file and it had correct values for 
"interrupt_psm" and "control_psm".

so, could you please double check your /etc/bluetooth/bthidd.conf file 
and make sure bthidd(8) uses the correct config.

i suspect there might be another bug in bthidd(8), so if you could 
please try to run bthidd(8) under debugger and try to examine internal 
configuration structures after bthidd(8) parses the config file.

i also attached a patch that renames global variable to avoid name 
collision with the local variables. i do not expect it to fix your 
problem, but please try it anyway.

lets not blame the hardware just yet :)

thanks,
max
