Issue with multiplayer using a PS2 USB adapter

[luk234]

Hello everyone.

I've been having problems setting up this specific adapter for multiplayer.
Adapter image
The adapter works great for single player, but when I try using both ports for multiplayer, I can't get both controllers to work at the same time.

In controller.ini, if I set MultiIn=1 and MultiInValue=01, only the first controller works. Changing MultinValue to 02 makes only the second controller work.
But if I set MultiIn=2, I actually get a response from both controllers, but they don't work the way they should.
This happens for all games, but is most notorious in SSBM. With both controllers plugged in, I navigate to the rumble menu, and I see this:

Player 1 controller is plugged in, for a short interval (~2-3 seconds), then P1 is unplugged and P2 is plugged in right after, P2 stays for a short interval (~2-3 seconds), after which the controller is unplugged, and the process repeats.
I can provide a video if necessary.

Are adapters like this not supported? or am I not configuring something properly?
Thanks in advance.

if its an hid adapter it should work as long as you made the controller ini correctly.

EDIT: added gif file showing the issue

Interestingly, my adapter is recognized correctly. Even if I don't use a controller.ini file, nintendont recognizes it as a ps2 controller. The problem is setting up multiplayer. Whenever I set multiin to 2, stuff goes crazy. I can't use both controllers at the same time without them alternating every 2 seconds.
This is the controller.ini file I'm using. Any help is appreciated.
