Originally posted by **williamdsw** November 30, 2023 Hi, how are you doing? First, thank you for your work. I do have some BlueRetro adapters and they work great. Second, I'm trying to connect a bluetooth mouse and a bluetooth keyboard to my dreamcast, and trying to use on Dreamcast Web Browser. I've set the mouse on port 1 with default mouse settings, and the keyboard on port 2 with default gamepad/keyboard settings. Although they pair and appear connected on device list of the browser, I got no input response for both, while they work perfectly on PC. I'm using the DC adapter and 1.9 firmware. Also I'm attaching both pcapng files for the mouse & keyboard. Thank you for your time. [Keyboard & Mouse pcapng.zip](https://github.com/darthcloud/BlueRetro/files/13519901/Keyboard.Mouse.pcapng.zip)

HID side of it is working fine as shown by using my trace_replay script:

The problem is most likely at the ATT attribute discovery level.

I can't replay that part of a trace yet. That would need a significant improvement to the script and to add the proper hook into the FW.
