Beaglebone USB connection Virual machine

[Remy Donken]

After the following commands i can't get a connection in Virtual machine.

1. Rev C: Open the file /boot/uboot/uEnv.txt in an editor (vim/nano)
2. Add the key "capemgr.enable_partno="
3. Add the ports you want to enable, comma separated (BB-UART1, BB-UART2. BB-UART4, BB-UART5)
4. Reboot

In windows it is still working with Putty/SSH or webbrowser but in Virtual machine with ubuntu it doesn't start the FAT partion 

Also cant login over the webbrowser or SSH.

can someone help me?
