No USB devices available

Post by ct2034 »

:cry: Hi,
I am running Ubuntu 12.04 with VirtualBox and a Windows 7x64 as guest. But I can't mount any USB devices, they are all greyed out. I used to work, but now it doesn't. I tried already several things:

This is NOT a problem of vboxusers group! I am in this group:

Code: Select all

ch@ch-laptop:~$ id
uid=1000(ch) gid=1000(ch) groups=1000(ch),4(adm),20(dialout),24(cdrom),46(plugdev),105(lpadmin),119(admin),122(sambashare),127(vboxusers)
Another solution i tired is this one:
Edit /etc/fstab and add:

Code: Select all

none /proc/bus/usb usbfs devgid=XXX,devmode=664 0 0
but I can't add the folder usb to bus, maybe because I'm using 12.04 ..


Please Help me, I tried everything!

Are there different Extension Packs? (cause u r using plural ..)
I have re-installed the regular one (which is the only one, i believe)
It didn't changed anything, but thanks for your answer.

Isn't this obvious? Each release version of VirtualBox has its own matching extension pack. The version numbers reported by VirtualBox and the Extension Pack should match.

I had assumed you had found your problem and the reply was to holzdog. Are you still not able to use USB devices and are they still greyed out for you?
