I've had this problem for a long time now but was always content to just use a virtual machine but now I need to get it fixed.
The problem is, when I plug in any of my Arduino's (they are all clones), and look under the dev folder, I never see any usbserial device. However, when I go to system report, I can see it there as a generic USB 2.0 device, and I can assign the device to a virtual machine and use it from a VM, but it never shows up on my mac as a usable device.
I can use other USB devices without any issues at all, even USB to Serial adapters work (like when I'm consoling into a Cisco router for example).
I tried replacing the IOUSBFamily.kext with one from the original install .DMG file, and I tried installing the latest CH34X drivers (1.4 I believe) without success.
Anyone out there have this issue who was able to solve it?
Thank you,
Mike Sims
