jordanvanbergen Posted September 27, 2005 Share Posted September 27, 2005 I get this message when booting from usb external disk on Acer 1520."com.apple.iokit.iousbmassStorageClass" has no kernel dependency. Any one have this problem? USB stuff is crappy on acer aspire 1520. You can't set anything in the bios only disable/enable and I'm also not able to use USB harddisc or a USB memory stick. As soon as you pop it in you'll get an error message after 40 seconds or so that you have to shut down your mac. Only my USB mouse is working, other "HIGH SPEED" USB stuff won't work. I saw that my Memory stick showed up as a "high speed bus" USB device. Those doesn't seem to work. Maybe someone has a solution for this?

cygeus Posted October 23, 2005 Share Posted October 23, 2005 I get this message when booting from usb external disk on Acer 1520."com.apple.iokit.iousbmassStorageClass" has no kernel dependency. Any one have this problem? I've the same problem. Booting from a usb 2.0 external hdd. It seems to be a problem with the hard disk. I also get the error message: "bdevvp: open failed" and then a kernel panic. Did someone get it working on a external usb/firewire hdd?? Link to comment Share on other sites More sharing options...
