Hacking Rock Band 3 Mic Issue

[superbob]

Hi folks !
I'm having strange problems with RB3 and mics.
RB2, RB1 and The Beatles Rock Band are working fine but RB3 doesn't work correctly.
When I play with only the guitar, it's fine.
When I play with one mic directly connected to one of the 2 USB ports (HDD in the other one), it's approximately fine (no points counted in games, but it recognizes my voice correctly).
When I plug the USB mic through the guitar hub (Beatles RB guitar), the mic doesn't work at all.
There is a really loud noise wether I play with guiter+mic or mic alone.
Sorry if it has been discussed before, couldn't find a clear answer to my problem.
I've got The Beatles RB instruments + GH6 instruments (including mic).
I've played with Hermes cIOS222/223rev4 (IOS36 merged with IOS37) and USB loader GX.
Guitar hero 3, RB1, RB2 are working fine with it (USB Loader GX/cIOS222rev4/IOS36 merged with IOS37).

Up, anything new ?

When that happens to me (the loud noise), I unplug the mic and plug it back in. Seems to work fine afterward.

Have you tried other slots?

I only have the Beatles game (no Beatles instruments) but I use 249r20(56) for all guitar hero games, and 224(57) for mic games. give these a try.

Have you tried to put a PC USB ports HUB on the second port on the Wii and plug your mic and guitar to that USB HUB ?

If not try it... Good luck...

It works !!!
I've updated my cIOS from v4 to v5.1 (223 using IOS37 as base) and it works correctly now.
I also updated USB Loader GX to 2.0, maybe it helped ...
Just did a bohemian rhapsody mic + guitar to check

No more loud noise.
