Re: [Bluez-users] Re: diNovo/MX900 problem with hidd

["Patrick W. Healy" <phealy@phealy.com>]

Sorry, I wasn't clear. I can make a connection, once, for a short time. 
After I've done so, the connection gets "lost"; it doesn't work until I 
pull the batteries on the device and reconnect with hidd --search. Could 
you possibly direct me somewhere to an exact set of steps to try so that 
I can try exactly what you know should work?

Thanks,

Patrick
