Hi all,

I know I'm replying to very old post, but I recently figured out how to make controllers work on PS2 emu (on PS3). Let me share my knowledge.
I used BeagleBoard-xM to analyze "hori real arcade pro v3" - an officially licensed and simple controller.

It worked well on PS2 emu and I didn't find any special packets (magic packets) passing through.
Then I noticed that PS3 is checking controllers' device descriptors and/or configuration descriptors. Unless they are in PS3's whitelist, PS3 does not start polling for hid report (even if the report descriptor of a controller is same as that of dualshock3).

Here I attach descriptors. It will work on PS3 with latest firmware.
Note that only first 3 bytes in hid reports are significant (Button_states_byte1, Button_states_byte2 and POV. details below) and following 24 bytes are fixed (128,128,128,128,0,0,0,0,0,0,0,0,0,0,0,0,0,2,0,2,0,2,0,2).

Assignment of keys (low bit first)
Button_states_byte1: Square, Cross, Circle, Triangle, L1, R1, L2, R2
Button_states_byte2: SELECT, START, L3, R3, PS, -, -, -
POV: 0x00=up 0x01=up-right 0x02=right 0x03=right-down 0x04=down 0x05=left-down 0x06=left 0x07=left-up 0x0f=none

Thanks for sharing this. Could you please check if GIMX 8.0 still has the same issue with PS2 emu on PS3? It contains an updated EMUPS3 firmware.

Matlo,
I didn't see your message, sorry. I will check it within a day or two.

I used Dualshock 4 with GIMX 8.0 + up-to-date EMUPS3. (.hex file is automatically updated while updating GIMX to ver 8.0, right?)
It worked on the home screen. All buttons including PS button was functioning.
However, after launching a PS2 game, the controller was automatically detached (it is normal. you usually need to press PS button again to reconnect) and the controller did not work any longer. I closed the GIMX session and reconnect the controller, but nothing happened.
I shall be happy if it can be of any help.

Thanks for the feedback. Could you please generate debug log files with "controller" and "usb_con" enabled? One before starting the game, and one after.

I took logs for following 4 cases.

1. Before starting games (at home screen), I started and ended GIMX.
2. After starting the PS2 game (beatmania IIDX 16 EMPRESS), I started and ended GIMX.
3. At home screen, I started GIMX. Then I started the PS2 game (by sending "Circle" keystroke using GIMX) and ended GIMX.
4. After starting the PS2 game, I started GIMX. After quit the game (this operation was done by another DUALSHOCK3 controller), I ended GIMX.

Case 1 : https://pastebin.com/8UgF2kaA
Case 2 : https://pastebin.com/V4HJu6fv
Case 3 : https://pastebin.com/PTcrsVxH
Case 4 : https://pastebin.com/14FpkF9u

In case 1 and first half of case 3, the controller was working (only at home screen). In other parts, I could not see any response on screen although keystrokes were dumped.
Just in case I masked the username. 「アクセスが拒否されました。」means "access denied".
I used an adapter made of FT232RL (http://akizukidenshi.com/catalog/g/gK-01977/) + Arduino Micro.
Please let me know if you need further information.

Sadly the logs you provided don't have the debug flags "controller" and "usb_con" enabled. Make sure to select "debug" in the "Messages" drop-down menu.

Do you have any news on this?
