zeroRPGmaker Posted July 29, 2011 Share Posted July 29, 2011 Trying to use Nawcom ModUSB because my blue-ray fails to read SL disk, and this is what I get: EHCI controller [1002:4396] at 00:12.2 DMA @f9fff800 Setting Legacy USB off on controller [1002:4396] at 00:12.2 Legacy USB off Done EHCI controller [100:4396] Why is it having a problem with my USB drive (ADATA 16g super series) or any USB drive? If I use ModCD and SL disk (with no USB drive attached), it does not have a EHCI problem. However, my blue-ray drive will fail to read the disk half way through (this is fault in the type of disk drive I bought). So my only solution was to use USB, but its just wont boot up Can anyone explain why it wont use a USB drive?
