Re: USB device doesn't appear on Mac

There are alot of potential differences in the descriptors for a USB CDC device. My guess is there is some difference between the Pololu descriptor and the Roboclaw one. The fact that the board works on some Linux computers and not your embeded one means there it probably has somethign to do with the version of the kernel or drivers installed. Since those are all up for grabs there isnt much we can do directly. You need to dig into what if any errors are being logged when you blug the Roboclaw into the one lInux computer.
As for the Mac, we currently have a Mac Mini we use for testing. I will have to check what OS version it is currently running. We arent Mac people in day to day use so Im not actually sure what the latest OSx release is. its possible your problem is related to an update made, or if your OSx is out of date that could be contributing to the problem.
However I will say that CDC devices are pretty simple. It basically all comes down to the USB descriptor. There should be logs on the MAC(just like on the Linux box) that can shed more light on your problem.
