USB Passthrough Keyboard sometimes does not detect keystrokes

Reported by: NilsK Owned by:
Component: USB Version: VirtualBox 5.2.6
Keywords: USB Keyboard Passthrough Cc:
Guest type: other Host type: Windows


Hi there!

I use Virtualbox on Windows 10 and have a Ubuntu 16 VM. I attach a seperate USB keyboard and mouse to the host and pass them through to the VM. This is pretty nice because with additional screen where the VM is in fullscreen mode, its almost like having two fully operational computers.

Everything works fine with the rather old version 5.0.8 r103449 of VB. I noticed that with later versions it happens that sometimes keystrokes get lost / do not get detected in the VM, especially when typing fast. The latest version I tried and I can still reproduce that behavior is 5.2.6 r120293 (Qt5.6.2). I always have the guest utilities updated and installed but they seem to have no effect here.

I really would appreciate you guys looking into that issue and fixing it, it worked in the past so maybe it's an small and easy fix. Unfortunately it's what keeps me from updating to later VB version.

Thank you and best regards, Nils

Have you tried to enable USB3 in your settings?

Just a friendly reminder; you remember the requirements in the new ticket page? They're actually listed before the ticket form, so I'm not sure how you missed it:

Attach a (full) log file ("Machine" menu/"Show Log" in the main VirtualBox Manager window) straight away to save time for you and for us. The log file contains a lot of useful information about both the host and the guest systems as well as information about what happened during a particular machine run. Please do not cut and paste it.

Socratis, you are a genius. Installing the expansion pack and switching to USB 3.0 fixed the issue. I wasn't aware of that. Thank you very much. Ticket can be closed.

May I suggest something? It's usually better and faster, if issues get first addressed in the  VirtualBox forums. More than 95% of the issues are resolved over there, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is not a bug and someone from the developers has to deal with it and close it as "Invalid" or "WorksForMe".

Keep that in mind for the future. Glad you got it going... ;)

Okay, I am sorry for doing those things wrong, I promise I'll do it better next time. Cheers!
