Cannot access USB with Virtualbox 6.1.32 r149290 on 20.04 host

cn flag

I came across this problem before. The workarounds below used to work. But it just doesn't work this time.

Basically, I have tried to modify vboxdrv.rule

and

sudo adduser $USER vboxusers

but none of them works.

I think it probably has nothing to do with permission since

sudo VBoxManage list usbhost

returns none as well

And

sudo lsusb 

doesn't return anything suspicious though

Anyone has come across this before? I want to diagnose it somehow but I don't know where to start. Any log can I check when VirtualBox guests can't access USB?

After you added yourself to the `vboxusers` group, did you log out and back in or reboot?
cn flag
yes. I did. I rebooted several times but to no avail.

+1 for visibility. Hmmm, I am not sure. Last thought is possibly missing the Extensions Pack. I have the same version installed and the same OS but all my USB devices are showing up. If you have it installed, hopefully someone else might have experienced the same thing and will be able to help. I am sorry that I am not much more help from here.

yes, i installed extension pack as well. i checked under preference and it is showing the same version as virtualbox. Sorry for forgetting to mention that.

Did you make sure to select USB 3.0 in VirtualBox's settings for the VM?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
