USB Loader GX freezes when i insert USB drive?

There is a pinned thread at the top of this subforum for GX support, but since you're already here:

For USB Loader GX you only need d2x in slot 249. It will load on IOS58 with AHBPROT enabled but Wii games won't run.
Most people use slots 249, 250 and 251 for the 3 patched slots.
You didn't mention whether you're using a Wii or Wii-U or what drive you're using... and are you SURE it's the right port?

 

If you're using d2x then it should be the USB port closest to the edge of the Wii. The "alt" version of the later d2x patches works with both but it doesn't work very well with emulated NAND.

As far as I know none of the Gamecube loaders (DIOS MIOS, Devolution, Nintendont) only use IOS58 so the custom IOS don't matter.

 

If you install the patched IOS56 in 249 and IOS57 in 250 then USB Loader GX shouldn't need any extra configuration for the majority of Wii games. There are a few that you may have to override the default setting for the specific game. (I think Just Dance requires that, for example)

Once you have those installed in the right slots if your drive still isn't getting recognized then it may be the actual drive or enclosure that's causing the problem.

 

I don't use that usb loader, but it sounds like it isn't recognizing the usb device. Have you tried a different usb device to see if it's recoginzed? Also, the Alt version of d2x has less usb compatibility, so what I'm saying is that d2x v10 beta52 has better usb compatibility than d2x v10 beta53 alt. For me, I have to use beta52 because beta53 alt will not get my usb hdd recognized.

 

Check the ISO hashes with the tool in my signature. If they don't match then they may be bad and need to be re-ripped. If the tool crashes it's probably because redump.org is down again.

I've never heard of DMLizard but the files should be named "/games/Game Name [TITLEID]/game.iso". The second disc of two disc games should be named "disc2.iso" and make sure the ISO names are lower case.
You might also check and see if they work with Nintendont. DIOS MIOS hasn't been updated in quite a while.

 

I would, personally. If for no other reason because it works with games that have streaming audio like Ikaruga, Eternal Darkness and Starfox Adventures.

It works about as easily as DM for USB Loader GX. There are modded versions of CFG Loader and WiiFlow that can boot with it as well. You just need to change which one you are using in the features menu. There are other options for memory cards, etc. too.
