Pavel,

Then the interesting test is to see if the delay is kernel or phone.   Are you talking
to the same phone with both adapters?  If so please copy me on any test patches as
I too have the same issue when talking to a pilot T3 using rfcomm using a "0a12:0001 
Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)" usb dongle.

I would _love_ to get 25K/s

Thanks,

Ed Tomlinson
