Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I have a VirtualBox ubuntu guest running on a osx host. I've searched the web and implemented the solution for similar problems, but nothing has helped me resolve my issue.

When I connect my phone, ubuntu mounts the device automatically. When I connect my USB drive (Kanguru SS3 32GB), it does not mount the drive. I'm only using one processor for my VM settings. VirtualBox has the device available and selected under the "USB Devices" menu, but the /media/ folder is empty and the drive does not automount.

So I don't know what to do at this point. Seems like overkill but should I uninstall/reinstall VirtualBox? Why would the guest os mount one usb device, but not the other?

some devices need an USB filter rule to be recognized. See askubuntu.com/questions/209950/…. –  Takkat May 8 '14 at 19:33
@Takkat I added a usb filter but it is still not recognized. One thing of note is that I don't have the 'vboxuser' group and I'm not sure how to get it. Some of the solutions to similar problems have suggested that adding my user account to that group will solve the problem, but I don't have that group available to test it. –  mblPrgr May 8 '14 at 19:49
The group vboxusers (note the trailing s!) should have been created on installing Virtual Box. Also see askubuntu.com/questions/25596/how-to-set-up-usb-for-virtualbox but I have no experience on an OSX host. –  Takkat May 8 '14 at 20:05
