philippe94 Posted March 14, 2008 Share Posted March 14, 2008 Hi, I need help for my USB1.1 and 2.0. They are detected but no fonctional. I have an Asus K8V-X SE Mobo with a Chipset Southbridge VIA8237R. I have Zephyroth OSX Leopard 10.5.2 AMD EFI. All works fine, only USB. I read this http://forum.insanelymac.com/index.php?showforum=156 but didn't help me. USB Legacy Support is fully disabled in BIOS but I have -legacy paramter in com.apple.Boot.plist I run USB Prober, with some USB devices connected, you can see my printer and 2 USB Keys plugged, here a screenshot: but noone is mounted on the desktop or really detected - I can't detect my printer for example. dmesg | grep -i USB is KO: no output, no result, blank if I do kextload -v -t /System/Library/Extensions/IOUSBFamily.kext/Contents/Plugins/PCGenUSBEHCI.kext I have "PCGenUSBEHCI.kext is already loaded; so I think it's OK. I don't know what's happened? what can I do? Any help would be appreciated. If needed, I can join/add some log of USB Prober or additional screenshots.

VasH Posted March 14, 2008 Share Posted March 14, 2008 Try this: In terminal: sudo su - type your password rm -rf /System/Library/Extensions/caches exit If it works you can make a script that load at startup (but I don't know how) I've had similar issue, but after 10.5.2 update USB work flawless. good luck Link to comment Share on other sites More sharing options...
philippe94 Posted March 14, 2008 Author Share Posted March 14, 2008 Thanks for your reply, VasH Some questions before test it: - do I need edit com.apple.Boot.plist (remove -legacy parameter)? - after the command, have I to reboot Leo?

VasH Posted March 14, 2008 Share Posted March 14, 2008 you don't have to reboot, but you have to type the command everytime you startup, if you don't write a script that load automatically at startup. As for the -legacy parameter I'm not sure, I wasn't usign that option. Try without removing and see if it works. if not, you can decide if remove and retry.

philippe94 Posted March 14, 2008 Author Share Posted March 14, 2008 Fantastic Vash!! It works: my USB Keys are mounted and my printer HP PSC 1350 is here and fully fonctional Good jon, thanks But now I need a script to load at each startup! Tested without removing -legacy parameter from com.apple.Boot.plist and USB Legacy setting to [Auto] in BIOS. EDIT: Another problem: it seems that after 5 or 10 minutes, I need to re-do the command to empty Extensions Cache, otherwise, same problem as before: USB Devices are not mounted!!! But not very disturbing at all. Perhaps there is an esay to fix this (a script?) But, Thanks for all Vash Link to comment Share on other sites More sharing options...
alpha2zulu00 Posted March 16, 2008 Share Posted March 16, 2008 This problem was fixed for me after installing the latest System.kext from a real Mac running 10.5.2 Link to comment Share on other sites More sharing options...
