So it's a https://www.skooterblog.com/en/2011/09/16/dealextreme- adaptador-usb-para-dois-controles-gamepad-de-snes-super-nintendo-ou-sfc- super-famicom/#.XmeezHUzZPI ? I think you can try to enable more debug prints:
dyndbg='file drivers/usb/* +pt; file drivers/hid/* +pt' hid.debug=1 log_buf_len=32M ignore_loglevel=1 Then try to find out the differences in `dmesg -w` output while pressing corresponding buttons on each pad. Should make sure if input reports are generated from USB transport layer, and then if the events are correctly processed in HID layer, and finally why don't have input events for some buttons. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1866716 Title: With USB adapter 0e8f:3013 only one SNES gamepad works Status in linux package in Ubuntu: Confirmed Bug description: I have a USB adapter for two SNES gamepads. According to dmesg/lsusb it is a "HuiJia USB GamePad", "GreenAsia Inc." I have two SNES gamepads (both SNSP-005, but the PCB inside have different 1992, 1995 dates), both working with the SNES. If I attach both the gamepads to the adapter, only one works, always the same, so it does not seem related to the adapter ports. If I attach only one gamepad it works, regardless of the port. I used jstest to test the functionality. Curiously, when they are both attached, the broken one has only one button working (no D-pad, no start/select, no L/R), and while holding the working button, another one can be detected.
