your chipset was released in (it probably is a 1.1 compliant chipset) I
believe that >0x000000008FFFFFFF is the highest event mask it would support

The device appears to have identified itself as CSR firmware using Bluetooth
version 1.1.

I do happen to have the 1.1 spec lying around :-), for Set_Event_Mask it
says

0x0000000100000000
To                                          Reserved for future use
0x8000000000000000

0x00000000FFFFFFFF	Default (All events enabled)

The mask above looks ok (no undefined bits), but are they supposed to be
displayed in that order? (IOW, are the bytes in correct order?)
