MasterHouse Posted December 11, 2008 Share Posted December 11, 2008 Hi, I have a dual-boot machine (XP SP3 / OSX86 iDeneb 10.5.4) and use Acronis OS Selector. Everything is fine using PS/2 keyboard and mouse. When I try to use USB keyboard and mouse I have to enable "USB Legacy support" in BIOS. Doing that I have no USB working ports in OSX. Any suggestions? A kext for OSX or a boot manager that enables USB without use of the BIOS... Thanks a lot.

Lanceomni Posted December 11, 2008 Share Posted December 11, 2008 USB Devices not workingApproach 1: With this tip I'm not saying that you are going to make your USB devices to work, but it is worth the try. - Restart your PC and go into BIOS menu. Go to USB configuration section. Set USB Controller = Enabled. Set USB 2.0 Support = Enabled. Set Legacy USB Support = Disabled. - Save changes and reboot. - Boot into Leopard just with -v (don't use -legacy flag). - If it works, edit com.apple.Boot.plist and remove -legacy flag, if exists. Approach 2: download IOUSBFamily.kext extension (located here, in Utilities & Resources) that may work for you. Always make a backup copy of the extension that you are going to replace. If it doesn't work, boot in single user mode and restore the old one. See if this works. http://osx86.wikidot.com/known-issues#toc7 Also does your bios have a third option for USB?

MasterHouse Posted December 11, 2008 Author Share Posted December 11, 2008 Thanks for the reply. I have to have "USB legacy support" enabled in BIOS otherwise I don't have control over my USB mouse to choose the OS in OS Selector, so approach 1 is not for me. I will try approach 2 then. Thanks a lot. MasterHouse Link to comment https://www.insanelymac.com/forum/topic/140519-usb-problem/#findComment-995413 Share on other sites More sharing options...
Lanceomni Posted December 11, 2008 Share Posted December 11, 2008 No Problem. Post back and let us know if it worked. Link to comment https://www.insanelymac.com/forum/topic/140519-usb-problem/#findComment-995518 Share on other sites More sharing options...
MasterHouse Posted December 11, 2008 Author Share Posted December 11, 2008 Hi, With IOUSBFamily.kext I can boot to OSX and my mouse works but no keyboard. When I connect anything to a USB port the system freezes and I have to reboot. Any suggestions. Thanks a lot.

Lanceomni Posted December 11, 2008 Share Posted December 11, 2008 Your symptoms don't quite point to this problem but are your Kernel & system.kext versions matching? For Example: Kernel 9.5.0 System.kext 9.5.0 You can check your kernel version by typing this in Terminal: uname -a You can check your System.kext version by right clicking the System.kext (Found in System/Library/Extensions/) and selecting "get info". This usually causes problems where USB devices are only recognized when they are plugged in at boot but there are other related issues.

MasterHouse Posted December 11, 2008 Author Share Posted December 11, 2008 Thanks again. My Kernel and system.kext are both 9.4.0. That's for sure. I'm going to read the USB post.

MasterHouse Posted December 12, 2008 Author Share Posted December 12, 2008 Hello, I did everything that was suggested in that post with no success... I'm going to try another bootloader, maybe Grub, as some Linux live CDs see my mouse with "USB legacy support" disabled. Thanks a lot anyway.

mschilling Posted December 12, 2008 Share Posted December 12, 2008 Try iATKOS v5 as there are drivers included for keyboard support. I had to use the x86 one to get my laptop keyboard and trackpad to work. I realize that I had the opposite problem to yours, but there may be a solution there for you.

MasterHouse Posted December 12, 2008 Author Share Posted December 12, 2008 Thank you. I will try this too. MasterHouse Link to comment https://www.insanelymac.com/forum/topic/140519-usb-problem/#findComment-996624 Share on other sites More sharing options...

MasterHouse Posted December 12, 2008 Author Share Posted December 12, 2008 Thanks a lot, Lunux! It's working. I can leave "USB Legacy Support" enabled in BIOS, finally! Now I don't even need Acronis OS Selector anymore, I can use Darwin Bootloader. I have to do some more test as this machine is going to be a DAW (Digital Audio Workstation), so stability is everything. Again thanks a lot, Lunux MasterHouse Link to comment https://www.insanelymac.com/forum/topic/140519-usb-problem/#findComment-996833 Share on other sites More sharing options...
