djavocado Posted September 23, 2011 Share Posted September 23, 2011 Hi On Snow Leo 10.6.8, I seem to have a strange problem. My USB mouse, my usb keyboard, and all 3 of my USB Thumbdrives works with no problem.. But no matter what other device I plug in, it wont work. I have a USB midikeyboard (M-Audio Keystation 49e) and a USB Midicontroller (Korg Nanokontrol). When I plug in the Keystation nothing happens, my computer doesnt seem to register it at all, I know its not a hardware issue, cause it works perfectly in Windows. Also M-Audio says there should be no driver for this, it should be "class compliant" The same with the Nanokontrol.. should work "OOB" Any solution to find here guys? Thx :-) Andy Link to comment https://www.insanelymac.com/forum/topic/268754-some-usb-devices-not-functional/ Share on other sites More sharing options...
Gringo Vermelho Posted September 23, 2011 Share Posted September 23, 2011 What chipset does your motherboard have? Link to comment https://www.insanelymac.com/forum/topic/268754-some-usb-devices-not-functional/#findComment-1752115 Share on other sites More sharing options...
djavocado Posted September 23, 2011 Author Share Posted September 23, 2011 Intel P35 Express.. I think I have worked it out now.. I unplugged my keyboard, and plugged in the Keystation to a different USB port. This sort of fixed it. But sometimes Snow Leo "hangs" randomly - It just shows the circle-rainbow-cursor thing infinite.. I can move around the cursor, but every thing is "locked" - and have to hard reset to get back to work.. I dont know if thats related to this? Thx - Andy Link to comment https://www.insanelymac.com/forum/topic/268754-some-usb-devices-not-functional/#findComment-1752123 Share on other sites More sharing options...
Gringo Vermelho Posted September 24, 2011 Share Posted September 24, 2011 Chipset is Southbridge+Northbridge. P35 is the Northbridge, USB ports are on the Southbridge... which ICH version is it? Use Console.app to look for clues about crashes/freezes in System.log or Kernel.log. If you have freezes/crash issues, always boot with -v. This will show the kernel panic on your screen when it happens and help you troubleshoot. Otherwise you'll just get the "friendly" version, "you need to restart your computer etc etc" and this doesn't tell you anything.
