Hey guys. I know this is in the section for Wii, but I'm in a similar situation on the Wii U. I've got Rock Band 1, 2, and 3 installed through Tecon's injector. I have wired RB1 drums, RB1 guitar with dongle, and RB3 Madcatz keyboard. None of these connect once the game starts. The drums light up the drum symbol, but then the game starts and the buttons are not responsive and the light is off. The keyboard shows a red x through the keyboard light on it. I've tried updating cIOS as in this article here. I haven't been able to find any recent threads, just that link that was posted in another thread about getting the Rock Band controllers to work on a Wii U. Any help would be appreciated!
