[beagleboard] Can't connect to USB serial port (FTDI module isn't loaded, ttyUSB device isn't created)

I know for the evm335x (Sitara) I saw a note no virtual OS drivers emulation is too slow

I was also told not to ask for help on here when building from vmware its not opensource either (-:

I’m running a virtual machine of Ubuntu 12.04 LTS 32bit in VirtualBox on Windows 7 Pro 64 bit. I’ve installed the USB 2.0 drivers from the VirtualBox extension pack, I’ve disabled auto-mounting USB devices in Windows 7 by entering “mountvol /N” in the command prompt, and I’ve attached the USB Device “Circuitco BeagleBoneBlack [0308]” to the virtual Ubuntu machine.

Still no ttyUSB entries in /dev. I noticed that the mkudevrule script is for a USB vendor id of 0403 and product id of a6d0 but the BBB entry in lsusb has a vendor id of 1d6b and a product id of 0104. So I changed them in the udev rule, reloaded the udev rules, logged out for good measure, and reinserted the BBB. Still no ttyUSB entries in /dev and no ftdi_sio or usbserial module in lsmod.

I checked “cat /proc/devices | grep -i ‘ttyUSB’” which gave me “188 ttyUSB”. I then checked “sudo cat /proc/tty/driver/usbserial” which gave me “usbserialinfo:1.0 driver:2.0” but no entries for FTDI serial devices.
