I posted this in the 5.4 thread, but this is probably a better place. This issue occurs with 5.3.1 (the 1st version I used) to the current version.

The USB 3.0 - Universal option makes certain drives cause my computer to freeze as soon as they're plugged in. My motherboard is an Asus Maximus V Extreme with an i7-3770K. I did a clean install without that option selected and the same drives work fine, except my Asmedia USB 3.0 ports don't work. As soon as I install the USB 3.0 - Universal option the drives cause OS X to freeze again. I'm using PJALM's Maximus V Extreme patch on his DSDT patch repo.

The drives causing the freeze are: HGST Tour0 Mobile 500GB portable, Lacie d2 2TB desktop, and Seagate Backup Plus for Mac 1TB. Strange thing is if I connect the SATA-USB3 interface from a non-for Mac version of the same drive it works fine. Use the interface from the "for Mac" version on the other drive and it causes the freeze. These drives all work fine in USB 2.0 ports with USB 3.0 - Universal installed.

Other USB 3.0 drives I tested that work in the USB 3.0 ports with no issues are: WD My Passport 500GB portable, G-Technology G-Drive mini 1TB, G-Technology G-Drive 2TB, Seagate GoFlex portable 1TB and 1.5TB. Lexar USB 3.0 thumbdrives I have also work.

Yes, i saw that. But it came as a suprise that it solved my Lacie Rugged/Asmedia USB3 port issue!

MB gives me installation error when i use MB to install it. The seperate kext using kext wizard is fine.
