I have recently added 14.04 bare metal to my computer. I am running VirtualBox (called VB from now on) and have several VM's that work exceptionally well except for one thing: I cannot get my VM's to see any USB flash drives. Stats: VB 4.3.12 linux. Host and VM are both 14.04 and are fully updated. Guest additions and extension pack are installed. I can verify that guest additions is working fine since I am using the VM to type this post. I really only want guest additions for the full screen and no other additional features are needed. I installed extension pack (for usb support) but I don't know how to verify all is well. Background: I also have 7 Pro on this machine and the windows side of the house works fine with VB. I have three or four VM's and all of them see and use usb without any issues at all when in "windows world". I mention this to eliminate the computer from the equation. My computer has 3 USB3 ports and 1 USB2 port. Not even the usb2 sees any flash within the VM's while running the linux host. The host 14.04 OS sees flash drives perfectly fine. Looking for suggestions on what I may try to capture usb flash drives from within linux on the VM's?? Should I delete and reload extension pack?
