Thanks for your reply. I was mostly copying other peoples' bootflags in hope they would work. I removed them all and am now just using -v -s and USBLegacyOff=yes. I tried to reset the USB stick but was prompted with a message along the line of 'missing media'. Unfortunately i'm still getting the same message, I tried a Yosemite installation too and was still met with the same message. I also realised there was a warning above stating "IOBluetoothHCIcontroller Search for transport event handler - Missing bluetooth control transport" then the 'Appleusbchi' error comes up and then messages loop. I'm not sure if they're related or not. I found some topics on the IOBluetooth problem, so I will research and try the fixes. If they don't solve the problem I will return to pick your brains. ~ Thanks, Tom

Hi, I used Myhack a few years ago and had no problems with installation. I recently tried to duel boot my pc, but I am unable to even get to the installer. It would say something like 'cannot find root, waiting' so I booted up in verbose mode and found the installation was getting stuck on this; "AppleUSBEHCI::Found a transaction which hasn't moved in 5 seconds on bus 0x1a, timing out! address = 3 Ep=0" I've tried everything so far, different bootflags, moving the usb stick to different ports, unplugged all usb ports apart from the keyboard etc. I can't work it out, I've spent the past 2 hours on google trying to find an answer and nobody knows! Any help would be greatly appreciated.
