Oh, but it works just fine before the usb3 patch...:-?

oops, but one of my hard drives that connects to a self-powered hub still lose connection after wake:wtf:

A little update, only those devices which were connected to a USB2/3 hub disconnect after wake, no problem for those which plugged on a native USB port, maybe related to the HUBN thing in DSDT?:crazy:

Before the usb3 patch, all of them work after wake from sleep, strange:eh:

Hello SJ, I experienced that the USB2.0 devices will lost connection after wake from sleep while the USB3.0 devices are fine, in my case, even my bluetooth dongle has to be re-plugged, any clue?:crazy:

However, I discovered that only the USB2.0 devices will disconnect after wake from sleep, while USB3.0s are fine :wtf: any clue?

Thanks a lot Giacomoleopardo for the detailed guide! I even got my Intel DQ77KB's USB3.0 fixed, now they are able to use USB2.0 and 1.1 devices:clap::clap:

Thanks, i remade my DSDT freshly and everything works fine now including sleep and wake:mrgreen: but 1080p youtube still lags, trying to tackle it with AppleGraphicsPM moddification:headbang:

Still no luck with sleep, i think it is related to the bluetooth dongle, anyway thanks. btw, do you guys able play 1080p youtube smoothly?:crazy:

attached is my DSDT, edited the _PSW to store Zero for both EHC1 and EHC2, removed the _PRW from XHC but still unable to make the system sleeps as it should (firing up immediately from sleep but with black screen, hanged):banghead::banghead:

I got a couple of errors after doing so, can you post your DSDT for my reference? p.s. using 0049 patched Bios:angel:

Through an USB 3.0 4-port Hubs, then you can use USB 2.0 devices on the hubs

A little update on my system, just got an USB 3.0 Hubs and able to use USB 2.0 Device through it finally:clap: But still looking for solution to get all USB 3.0 ports work. Btw, looking for a mini PCI-E WiFi Bluetooth combo card, is that the Atheros AR5B195 works natively without installing...

found a new problem which I think is related to the bootloader, everytime I do a cold boot, the POST said "A bootable drive is not found", but I can boot by pressing F10 and select the SSD, at the meantime, there is no other storage device connected to the board:crazy: any solution I can get rid...

Great, installed sucessfully but still need a fix for usb, and sleep doesn't work too (without DSDT):angel:

Hmmm.... I used the built-in usb 3.0 port, is that the reason?:shock:

Hi mactester, I just bought an exact same hardware config as yours and I am stuck at installation with "still waiting for root device", any flags needed during setup? Thanks:banghead::banghead:
