Dreamcast keyboard no response

[rpf16rj]

Hi, how are you? I hope fine!

I am try use keyboard on a Dreamcast. I made a adapter and he work fine with a bluetooth PS4 joystick. When i try use in keyboard mode (i setted the mode to Keyboard and preset Gamepad;Keyboard), the kayboard show connected on Dreamcast but no response of keys.

I tested that this version of fw in this thread and the lasted 1.8.3.

In another devices, the both keyboards works fine.

I tested with two models of keyboards bt, a Microsoft Mobile Keyboard 6000 and a generic bt keyboard chinese. I atached the debug log below.

Thanks for you time.

HID parser look to be working for that one. Issue look to be in the handling of fragmented packets used for the HID descriptor. I will have to investigate further.

I dont have the trace for the MS 6000 KB but from the log this look to be a HID parser error: # 1 # Unknown HID marker: 1A

Can you try this beta with both the Microsoft 6000 and the Chinese.

This should fix the 2 issues i saw in the log/trace

Hi, i can confirm that MS 6000 work now. Chinese doesn't work.

[darthcloud]

Can you get the serial console again on that beta while connecting the Chinese one?

Thanks for the log, that keyboard descriptor is simply very unusually big. I doubled the size available and it still dont fit.

It won't be possible to support it in BlueRetro unfortunately.

Thanks for providing the logs and sorry for long delay. At least the MS one work now.

[rpf16rj]

Thanks for add support to MS Keyboard 6000.

Fixed in v24.04
