Hi
This is probably of limited use but one can see from your hciconfig 
output your dongle hit a trouble. Here's some cut'n-paste from one of 
the CSR developer manuals of the meanings:

>         Panic code:   0x16
An irrecoverable error has occurred within the Bluetooth Link 
Controller.

>         Fault code:   0x1e
Either the chip received an unrecognised RFCOMM (upper interface) 
command message from the host or the chip ran out of pool memory when 
processing the message. In either case the message has been discarded. 
Presuming the fault was issued because of an invalid RFCOMM message, 
the firmware has survived the problem. 

Since your dongle seem to do a reset it "looks" like the mem pool ran 
out. But this is only a gues of mine. Is the error reproducable when 
using MS-Windows? In that case the donge firmware might need an update.
