You have 249 based as 57 and 250 that couldn't be identified.
It's best to use at least d2x v8 (but not v10 beta53) and install it as IOS 249[56] and IOS250[57]. As you have it should work ok with most games but some don't run on 57 properly and require 56.
The CSG is wrong on that account. d2x-v10-beta53 is not recommended. It is only useful if you cannot use port 0 on your console and has compatibility issues with games.
Your drive isn't partitioned properly and/or you have no IOS 58 or it's patched or corrupted, then. That has nothing to do with USB Loader GX. (The latest version of it is r1262, btw.)
