Administrators Bronxteck Posted January 17, 2013 Administrators Share Posted January 17, 2013 then you have to see what kext it is using that is working. and see if it is loading on your hack. then start troubleshooting from there. to see if it is a hardware or software conflict.

geyouncherf Posted January 19, 2013 Share Posted January 19, 2013 Newbie question (sorry): how do i look what particular kext a specific device is using ? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted January 19, 2013 Administrators Share Posted January 19, 2013 First of all, kexts usually have meaningful names... Eg: '80211xxx' obviously relates to Ethernet/networking, 'ATIRadeonX1000' obviously relates to ATI Radeon X1000 series graphics cards, 'xxxPS2xxx' obviously relates to keyboards and mice, 'IOATAxxx' obviously relates to disk controllers, etc. If you know ziltch about computers/IT technology, you're up for a challenge! Secondly, OS X does not load a device-related kext unless it is required. For example, if you have an nVidia graphics card, it won't load the ATI or Intel drivers, only the relevant nVidia kext. Naturally, you're expected to have the correct kext that supports your HW... To spice things a little more, sometimes you have to patch (=edit) an existing kext so that it supports your hardware! In such cases, you really have to get pretty familiar with your hardware and fairly computer-litterate. Link to comment Share on other sites More sharing options...
geyouncherf Posted January 19, 2013 Share Posted January 19, 2013 thanks for this - just to clarify: am not exactly computer-illiterate, just a newbie when it comes to fiddle around with kexts (no offense taken ... problem is that there is no change in the loaded kext's on my mac whether the iSight camera is connected or not (cleared the kext cache, rebooted without the camera attached, listed the loaded kexts, attached iSight, confirmed it's working, again listed the loaded kexts... no difference. so here the more precise version of my question: is there a tool that shows or way to find what (physical or logical) device is using what kext(s) ?

Administrators Hervé Posted January 19, 2013 Administrators Share Posted January 19, 2013 You can always try IORegistryExplorer and look at 'bundle identifier' information, but you may find the tool a little overwhelming and beware of plugins, which are kexts inside a kext...

jruschme Posted April 18, 2013 Share Posted April 18, 2013 Is this a power issue? I thought the 4-pin Firewire ports didn't supply the 24VDC. Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted April 19, 2013 Administrators Share Posted April 19, 2013 look in s/l/e and see if there is an isight kext Link to comment Share on other sites More sharing options...
