Hm.
So let me get this straight...
you are saying that initially, you didn't install cssu and you installed diablo turbo kinda...but not all of it.

If I understand what you said...I would suggest not installing and upgrading bits and pieces.
Not following through results in all kinds of unknown.
I myself found through experimentation, stuff that wouldn't work properly and some that did.
For a positive example... something that did work well I found...
I got 2 - 128 gb sdhc adata standard size cards recognized and to work in the n800 with normal diablo and cssu installed (but not diablo turbo installed) .
But with the next stage of updating...installing diablo turbo. After which point the device lost the ability to recognize and access the card. Odd. I'm still fiddling with the why of that.
But I do know partial installations of turbo didn't help me. (Experimented with that)
And most definitely installing diablo turbo without cssu won't help.
Just my opinion from all I've gone through or tried.
