I was thinking that it would be nice to play some Monster Hunter Tri for a long time. Then USB Loader GX said it doesn't find any USB devices. I tried other loaders as well, still no luck. Then I tried put my iPhone one of USB ports to see if they are even working. I noticed that USB ports stops working as soon as I'm in Homebrew Channel. My iPhone will charge in system menu and stuff, but after Homebrew Channel, nothing. Same thing for both ports. I've Hermes cIOS and cIOS249-v20 installed to my system if those will help. There was no any problems before.
