Debug CDC device on MAC OS X? Hi all, I'm trying to get a simple CDC ACM device working on my MAC. But i can't get Mac OS initialize the driver completely. It is surely something from my firmware but I can't point the problem. Here is the device descriptor as displayed by USB Probe. MacOSX recognizes CDC(-ACM) devices (ie. Virtual COM port) without ANY extra driver. Just plug in the device. You'll see two objects under /dev for the single CDC device, for example. Apple's developer documentation writes in a vague way that a codeless kext can be written to force a specific driver on a matching device, or prevent a generic driver to load for a matching device.
