I've been using cIOS38r17 for a while now because whenever I try to upgrade to a newer revision my game channel wads that I have installed no longer work. When I installed cIOSXrev20b (IOS56 v5661 in slot 249 and IOS38 V4123 in slot 250) I get this error when I load a game channel wad that I have installed. ERROR: Could not initialize USB subsystem! (ret = -6) Press any button to restart... I also get this error when I installed the latest d2x cIOS. Strangely enough whenever I reinstall cIOS38r17 my game channels work again.. Any ideas? Thanks..
