So we made a bit of progress, managing to get the BBB connected on all of the the new iMac's (Early 2014) running 10.10.2. In the end, it seemed that resetting PRAM & SMC after doing a repair of the disk permissions was all that was required. Why this worked is beyond me, it makes no sense. One of the five boards would work out of the box on all machines, all of them have the same image, so again it makes no sense unless its some strange voltage / USB timing issue?
The only mac giving problems now is an early 2011 iMac 27, its also running 10.10.2, it utilises the AppleUSBEHCI.kext (version 705.4.14) within IOUSBFamily.kext (Version 710.4.14) to drive the USB2 bus. A machine still running 10.9.6 (Late 2012 Mini) uses AppleUSBEHCI.kext (version 686.4.1) within IOUSBFamily.kext (Version 660.4.0), it has USB3. We tried moving the 10.9 IOUSBFamily.kext to the 10.10 machine, but nothing happened, the USB ports work fine but the BBB is not picked up. After the update, the USB is listed as "USB High Speed Bus" i.e. USB2. So, the difference is that this Mac has USB2 not USB3, all of the new macs use the AppleUSBXHCI.kext (10.10 version) to drive their USB3 hubs and not AppleUSBEHCI.kext. We will keep plugging away at it as a lunchtime / coffee break project to see if we can get it to work. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
