Hello,
I see USB dongle with Chip version: BlueCore02 (ES2).
What means ES2?
=46riend tried to flash firmware from manufacturer (rainsun), but it fails.
btdfu tells ""No such device".
This is in log:
=2D-----------------
Dec =A02 23:13:33 a /etc/hotplug/usb.agent: ... no modules for USB product=
=20
a12/ffff/209

a12/1/373
=2D-------------------
It's possible, that in DFU mode will be other ID?
a12/1/373 versus a12/ffff/209
Can be this dongle flashed with GENERIC firmware?

this means engineering sample of the BlueCore2.

The btdfu is not an official firmware utility. It may work or it may not
work.

In DFU mode the product id 0xffff is used and the version id comes from
the build id of the boot loader. In normal mode it is the firmware build
id.

This looks like the Billington dongle I flashed some time ago. This
dongle has only 4 Mbit flash and so won't get HCI 18.x on it. In this
case the HCI 16.14 from GenericCSR.dfu was used. And with the new
firmware the ES2 was gone.

Marcel
