Im having trouble attaching USB devices to virtual machines. FYI im no IT expert so please bare with me here!! Im running Ubuntu 20.04 as my main OS. I have 3 virtual machines (2 x Ubuntu 10.04 and 1 x Windows 10 pro). All is well with my current setup aside from the USB issue. I have installed Virtualbox 6.1.10 and I have also installed guest additions and extension packs.

I insert the USB and I can see it attaches and works fine in the main OS. But when I go to a VM and select devices>USB I get error message "Failed to create a proxy device for the USB device.(Error VERR_PDM_NO_USB_PORTS).

I read online that version 6.1.10 of virtualbox had bugs regarding this so I also have 6.1.2 installed. Could this be my conflict? Also within the Virtualbox VM settings i have toggled between USB2/3 option but this makes no difference.

I will be honest im dubious about uninstalling things on Ubuntu as im not familiar with the terminal commands.

Any help greatly appreciated, thanks for taking the time to look at my issue.
