The problem is in my controller or my dongle?
Fake DS3 Controller disconnect Bluetooth after 5s
@nefarius and this is trace log bthps3
[L2CAP_PS3_AsyncReadInterruptTransferCompleted]Interrupt read transfer request completed with status STATUS_DEVICE_NOT_CONNECTED (0xC000009D) (remaining: 0)
The controller just drops the channel connection, can't tell you why, most probably controller issue. I don't support fake DS3s for reasons explained many many times, you're on your own with this.
