Using CSR8510 dongle to pair Sony pads

[Shazz]

Hi,

I bought a cheap USB BT dongle said to be based on a CSR8510 chip.
It is somewhat recognized by MiSTer:

Code: Select all

[   38.966294] usb 1-1: new full-speed USB device number 2 using dwc2
[   39.146488] usb 1-1: New USB device found, idVendor=0a12, idProduct=0001, bcdDevice=25.20

[   39.146508] usb 1-1: Product: JL AC69 A10

But quickly some errors occur:

Code: Select all

[  248.163082] Bluetooth: hci0: failed to register connection device

When I enter in MiSTer pairing mode without any pad:

(Is the Logitech K400r BT ?) On the screen it says

Code: Select all

Got device: 38:B1...

RequestConfirmation (/org/blue

And when I plug a Sony PS3 pad, nothing is triggered at the BT level:

Code: Select all

Same for PS4 pad in pairing mode, nothing happen.

Can I conclude this dongle doesn't work ?

Thanks!

CSR8510 works fine. I have several such dongles from different manufacturers.
It;s most likely USB problem. Make sure you use powered HUB. Also try to change port on USB hub.

My hub is powered, I tried to change ports.. same results.
I tried other hubs, same results.

Is there a way to check this is a real CSR8510 without opening it ?
Or any command I can try to debug it ? (on MiSTer or on my linux laptop)

plug to Windows. Windows 10 shows the chip name as device in Bluetooth options.
