No rumble on Mayflash adapter

[whib]

The controller is working fine in Dolphin, but there is no rumble. I switched it to Wii U mode, plugged in both USB plugs, and installed the winUSB driver. I have rumble checked under controller settings, and any attempt to test the rumble yields nothing. Any advice?

I will contact Mayflash and ask about a replacement if we conclude it is faulty.

Bump.  Can anyone help me even test the rumble without a Wii U? I just want to know if the unit is faulty.

This will be my last attempt to bump in order to get help.
