influence Posted May 18, 2008 Share Posted May 18, 2008 All of my USB ports are working however Leopard is not detecting any storage devices, be it a camera, USB flash data stick or multi-card reader so I don't see them on my desktop. Is there a kext for this? Any help would be appreciated, thank you.

your mother Posted May 19, 2008 Share Posted May 19, 2008 Make sure that your USB legacy support is disabled in BIOS, having it enabled gave me all kinds of USB issues.

Wyseman Posted June 1, 2008 Share Posted June 1, 2008 I'm having the same problem, USB device (e.g. iPhone) shows up in System profiler but never connects as storage, doesn't shop up in itunes Same problem with TomTom go, USB HDD's, Pendrives etc. I'm also on a Gigabyte motherboard (GA-EP35-DS4) & Kalyway 10.5.2. Updating to 10.5.3 didn't help either. Edit: I have disabled USB legacy support in the BIOS and tried all the devices on multiple USB ports. Same issue each time. I did get the tomtom to connect once (having it powered on during a reboot), however it would not re-connect again.

kuru Posted June 1, 2008 Share Posted June 1, 2008 Restarting with the device attached works for me, however removing it and reattaching it loses it again. Since restarting isn't always convenient, you can also do this: In the terminal type: sudo kextload /System/Library/Extensions/IOUSBMassStorageClass.kext Now attach your device and it should be found. This only lasts temporarily though, and after a few insertion/removals of the device it will no longer be found and you have to type the command again.

Wyseman Posted June 1, 2008 Share Posted June 1, 2008 Been playing about with this a bit more, I noticed the following in the system log (/var/log/system) Jun 1 14:33:09 mac kextd[10]: a different version of dependency extension /System/Library/Extensions/System.kext/PlugIns/Mach.kext is already loaded Jun 1 14:33:29 mac kernel[0]: USBF: 10772.426 AppleUSBHubPort: Port 1 of Hub at 0xfd000000 about to terminate a busy device (iPhone) after waiting 10 seconds As i'm new to the whole osx thing, i'm a bit unsure where to go from here, google isn't helping! Any suggestions appreciated. EDIT: Found the answer, all works now: system.kext version didn't match the kernel version I was running. This is a problem with the Kalyway 10.5.2 DVD :censored2: Solution from the thread below, there's some really smart people around! http://forum.insanelymac.com/index.php?showtopic=95789 Link to comment https://www.insanelymac.com/forum/topic/105586-usb-storage-devices-not-detecting/#findComment-766250 Share on other sites More sharing options...
kuru Posted June 1, 2008 Share Posted June 1, 2008 Great find Wyseman, manually replacing the system.kext with 9.2.0 fixed it permanently for me too. That thread should be stickied...
