Hi,
Sorry for bothering linux bluetooth developers with my problem, but I was not
able to find any active users list.
I have this device plugged into my workstation:
# dmesg

Firmware check valid checksum
AFAICT, the device firmware doesn't provide HID proxy functionality, that I
would find rather usefull if present.
Is it possible to replace the device's firmware with one that can act as HID
proxy? Is Apple BluetoothFirmwareUpdate2.0.1.dmg provided GenericCSR.dfu
firmware compatible with BlueCore4? If not, what are my options?
Thanks,
Janusz
