I've been reading that HBC should be on IOS 58 in order to use USB 2.0 and if you are on another IOS say like me IOS 61 it is better to upgrade to system menu 4.3 or download the IOS 58 installer and reinstall HBC. The thing is I'm already on system menu 4.3 and through a system check have IOS 58 installed, but my HBC is using IOS 61. My setup works good, except WiiMC doesn't work, which isn't important to me. Is there any other drawbacks with my setup? Loaders also work good, but with occasional freezing in some games. Would changing to IOS58 fix game freezing? Thanks for any info you can give.
