USB flash drive no longer detected by VirtualBox

I never used to have this problem. I haven't used VirtualBox for some months. Today, my intention was to create a boot disk for the Intel Processor Diagnostic Tool using Windows XP, because two previous attempts creating (a) a boot disk; and (b) a boot USB drive from Linux have not been successful. I thought that perhaps using all the Windows software to create the boot disk from http://www.tcsscreening.com/files/users ... index.html might help it along a bit.

Unfortunately, I wasn't even able to capture the USB drive this time using the same method I have always used to capture a USB device in VirtualBox.

Now I'll see if I can work out how to get the screenshots into this post.

1. The flash drive is mounted in Linux.

2. What happens when I try to capture the flash drive in VirtualBox.

3. What happens when I hover over the "USB device" icon in VirtualBox.

I opened another VirtualBox client to make sure that it wasn't just this client that is playing up. The same thing happened in the Android 4.3 client as well.

None of you images made it. Post the guests log file as an attachment.

I noticed that thumbnails didn't appear for the images, but if you right click where the image should be and "Copy image address" the URL is correct.

I attach the current log file.

Do you see your user name in the vboxusers group on the host when you type id in the terminal?

It doesn't look like it.

Code: Select all

el_gallo_azul@W2600CR-850Pro:~$ id
uid=1000(el_gallo_azul) gid=1000(el_gallo_azul) groups=1000(el_gallo_azul),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),108(lpadmin),124(sambashare),127(boinc)
el_gallo_azul@W2600CR-850Pro:~$
How do I get it in there?

I imagine that it always used to be there, and maybe my recent distribution upgrade didn't work 100%, as I thought it had for the first time in my life.

In a host terminal run this:

Code: Select all

sudo usermod -aG vboxusers <your username>
Replace <your username> with the name you use to log in. Type your user password when prompted.


Be sure to log off and back in to finalize the change in permissions
