Hello,

thanks for perfect explaining.

I have good news. I flashed my dongle, and she is not dead ;-)

Dongle now starts in HID mode. I must switch her to HCI with hid2hci.
hid2hci says something, that it fails, but it works. I have probably old 
version of this utility.
Dongle in HID mode lights with power LED, but in HCI is power LED off.
Second LED blinks in both modes.

There are informations from hciconfig:
