I assume that the device node was created automagically by udev or some other type service running on your mac. udev makes device nodes like this with specific permissions, and sometimes they are restrictive because the device node is setup in such a way that a normal user can not use the device. Check the perms on the device and see if the user account you run vbox as can actually read and write to the device node. If the vbox user can not use the device node issue a chmod command till the vbox user can use the device. You may also have to chown the device to a new owner:group combination. Once you find a owner:group perm set that works with vbox then you need to configure udev to always make the file node the "right" way. > And under details- > > Error ID:DrvHostSerialFail > > And when I look in /dev cu.usbserial-FTKVMAFF > > Is gone? > > And my settings for my vm are > > Ports-->Serial Ports-->Port 1--> > > Enable serial port, checked > Port mode- host device > Create pipe, unchecked > Port/file path: /dev/cu.usbserial-FTKVMAFF > Nothing wrong here that I can see. Just make sure that the usb device that creates the serial port is not in a vbox usb filter setting. You want the host to control the usb device and the guests to access the serial device created on the host. It will work with box, I have a similar usb-to-serial device and I got it to work with vbox just fine. the device you plug into the serial port really shouldn't matter all that much.
