Hello,

Here are the files for the Fully working Asmedia USB 3.0 Controller (1042) in Mac OSX 10.7.3. I have tested this with my Notebook Asus K53SC. It can work in other Version of Mac OSX as well but I haven't checked, so give a try.

Everything works Sleep and shutdown but I haven't checked the performance with USB 3.0 devices since I don't have any USB3.0 devices but I'm sure it will work since the drivers are made for this chip itself.

For shutdown and Sleep to work, it needs a DSDT fix.

Here is the DSDT fix and steps for everyone who has Asmedia 1042 USB 3.0 Controller to try it.

Steps:
1. First, find where your device is connected by looking at the IORegistry using IORegistryExplorer app.
Example:- Mine was connected to PCI0->RP04->PXSX
2. Add the Following method to PXSX

Code:

 Method (_DSM, 4, NotSerialized)
                    {
                        Store (Package (0x0A)
                            {
                                "AAPL,clock-id", 
                                Buffer (One)
                                {
                                    0x02
                                }, 
                                "AAPL,slot-name", 
                                Buffer (0x07)
                                {
                                    "Slot-4"
                                }, 
                                "name", 
                                Buffer (0x18)
                                {
                                    "ASMedia XHCI Controller"
                                }, 
                                "model", 
                                Buffer (0x28)
                                {
                                    "ASMedia ASM1042 USB 3.0 xHCI Controller"
                                }, 
                                "device_type", 
                                Buffer (0x0F)
                                {
                                    "USB Controller"
                                }
                            }, Local0)
                        DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
                        Return (Local0)
                    }

3. Install the Kext attached and fix permissions

Optional Step:

You can update your firmware to latest version using the File (Firmware_Upd) attached.
For me everything working in this and as well as before firmwaresl.

UPDATE: Added the New and Fixed Kexts for Both Lion and Mountain Lion.

Hope it helps.
