Total control psx adapter to dc problem

My adapter seems to have a problem using a ps1 digital pad hacked for a sanwa joystick. The adapter will work great for a period of time then all of the sudden just stop working…ugh.:looney: Its brand new from ebay. The pcb looks good on the adapter. I also have a pelican ps3 to usb adapter also, it works great with that, so I don’t know what is going on…??? Thanks

Have you tried using it in different controller ports on the DC?

Nope does the same thing on port b. It works fine for awhile and then it cuts out and won’t read my joystick anymore. My second control is plugged in w/vmu port b. Thanks
