SonicArt Posted March 20, 2008 Share Posted March 20, 2008 Just out of curiosity, in the BIOS I turned off Legacy support for USB and next thing I know my front USB ports are working! I have a P5B-E board, but I think this should work for the other boards too.

Monty1157 Posted March 20, 2008 Share Posted March 20, 2008 Front USB ports will work fine with legacy enabled if you use the SMBios.kext from here. Should also sort out the system profiler to display your hardware a lot better. This won't enable any front audio ports, and the audio still only works stero out, no inputs. Just thought it might help. Link to comment https://www.insanelymac.com/forum/topic/94646-getting-p5b-front-usb-ports-to-work/#findComment-675142 Share on other sites More sharing options...
SonicArt Posted March 21, 2008 Author Share Posted March 21, 2008 Yes, I tried the new kext already and although there's more information about my RAM in the profiler, the front USB ports still don't work unless I disable Legacy support.

Gujal Posted March 21, 2008 Share Posted March 21, 2008 Yes. I have a P5B board and I have to disable legacy USB support in BIOS to get my front USB ports to work Link to comment https://www.insanelymac.com/forum/topic/94646-getting-p5b-front-usb-ports-to-work/#findComment-676181 Share on other sites More sharing options...
komeet Posted March 21, 2008 Share Posted March 21, 2008 AppleSMBIOS.kext just lists your hardware specs. It doesn't affect your system our OSX in any way. If you disable USB legacy support you can't boot from USB devices anymore.

Gujal Posted March 28, 2008 Share Posted March 28, 2008 If you are using USB keyboard and disable USB legacy support, the keyboard wont work in Darwin Bootloader, also any old OS (such as Win 95) However I recently saw an updated generic USBEHCI driver in the drivers section in the forum. This one supposedly replaces the AppleUSBEHCI and is reportedly working fine with P5B without disabling legacy USB support and works even with Kernel 9.2.2. I will try this tonight and report UPDATE: I can confirm that with Legacy USB Support Enabled and with the Generic USBEHCI Driver, the front USB ports are working successfully on my Leopard installation with 9.2.2 Kernel. Here is what shows up during boot USBF: 0.362 Found USBLEGSUP_ID - value 0x10001 - writing OSOwned USBF: 0.622 EHCI - Ownership conflict - attempting hard reset ... USBF: 0.622 EHCI - Force BIOS Ownership to 0 USBF: 0.622 acquireOSOwnership done - value 0x1000001 The driver can be found here Link to comment https://www.insanelymac.com/forum/topic/94646-getting-p5b-front-usb-ports-to-work/#findComment-686064 Share on other sites More sharing options...
