Inserting USB device cause Mt. Lion to Freeze

[elinato1]

Hey All,

I run into strange problem, my Mt. Lion working perfectly, beside when I plug in usb devices, if I plug in any USB device into my Mt. Lion after a few second it will freeze.

If I plug it into Mt. Lion before I start my Hackintosh I will have no problem.

Any suggestion to this problem????

Thank you

I was able to get rid of the system hang when any device was inserted into the USB 3.0 ports with a DSDT edit but as I don't have any USB 3.0 devices I'm not able to test if USB 3.0 is working properly now. Please upload your DSDT so that I can take a look at it. Maybe I can find a solution for your problem too.

Hello elinato1,

try this! I patched method _PLD of devices HSP1...HSP4 and SSP1 ... SSP4 to return a buffer in version 2 format instead of a buffer in version 1 format which resolved the issue for me. See sections 6.1.8 and 9.13 of the ACPI 5.0 specs (www.acpi.info/DOWNLOADS/ACPIspec50.pdf) for further details. Although I'm confident that the patched DSDT will work fine, as a savety measure you should always be prepared to handle kernel panics on boot while experimenting with DSDT edits.

Good luck!
