Is this the gamepad you were thinking of? Or would you like more information on other gamepads?
After some research, I found that:
The gamepad you're referring to is likely the "1949" product code from a vendor, with a product ID of "0402". gamepad -vendor 1949 product 0402-
The vendor with the ID 1949 is likely "Razer" or more specifically, a USB VID (Vendor ID) of 0x19d (which corresponds to 1949 in decimal). Is this the gamepad you were thinking of
