USB 3.0 Problem caused by faulty DSDT

12 May 2012 - 06:27 PM

My problem continues from the following topic. :wallbash:


The problem is that my USB3 ports only work after WAKE from sleep. :blink:

It is renesas usb3.0 with latest firmware.

PXHCD.kext is loading successfully.

if i plug anything to my USB3 port the system freezes and i have to restart the system.

my USB3 ports works only after the system is put to sleep and then WAKE from sleep. :blink: Then it continues to work OK.

Its not a driver problem or IRQ problem.

i have attached my DSDT and screenshots.

please help me solving this problem. :help:

PRO help Required in Post Installation

13 January 2012 - 03:52 PM

I am having a HP DV6 laptop with following configuration.

Core i7 2630QM
HD3000 graphics
AMD Readon 6770m 2GB
MAC Lion 10.7.0 and 10.7.2 Dualboot

facing following problems in both 10.7.0 and 10.7.2.

Problem-1: :fiery:
System have two USB controllers 1c26 and the other one is 1c2d.
to 1c26 controller 1.Ralink RT539f WiFI and
2.Ralink Bluetooth
3.2 USB3 Ports

and to 1c2d controller 1.True Vision HD webcam and
2.Validity Fingerprint Scanner
3.2 USB2 Ports
are connected.

Out of both, 1c26 controller with WiFI, Bluetooth and USB ports working correctly and
USB2 devices plugged are also being detected in this port,
but device 1c2d controller with True Vision HD webcam,Validity Fingerprint Scanner and usb2 ports
not at all working.
I know that there are no drivers for Validity Fingerprint Scanner for MAC OS but the webcam is not also working.
Whenever i plug any USB device to any of the 2 USB ports on this controller(1c2d) the system freezes and
i have to restart the system by pressing and holding the power button.

Problem-2: :fiery:
Secondly i have 3000 HD graphics and AMD readon 6770m built in and both are being detected
in system information(through DSDT edits), but i am unable to switch to AMD graphics.
I am only able to run with HD3000.
gfxCardStatus software says "please use a system with dual GPUS".
can anybody advise me how to enable graphics switching?

Problem-3: :fiery:
Follwing hardwares are also not working.
Ralink RT539f WiFi (0x1814,0x539f) on PCI-J6C2 : no drivers found yet
Realtek card Reader 5209 (0x10ec,0x5209) on PCI-J6D2 : no drivers found yet
Realtek 8168 Gigabit ethernet (0x10ec,0x8168) on PCI-J5C1 : driver is not loading for it

Any help will be highly appreciated.....
