Hello guys, i have installed IOS36-64-v1042.wad USB LOADER 1.5 HDD iomega (500 gb) and Rock Band Instruments Pack, which came with a usb hub to fit all instruments. and runs games normally. so when i play with the dvd of the game, its normal, but when i use the game from HDD and usb loader, it seems that the USB port for the hub turns off! cause there's a light and when the usb loader start the lights go off! and suggestion?
