Error message when booting into USB with Plop Boot Manager

[JoshIsci]

I have a USB with Kali 2.0 installed w/ persistence, and I made a virtual machine in VirtualBox and used the plopbootmanager iso under storage section, and I attached what I think is my usb under usb 2.0.

When I run the virtual machine and choose USB, it gives me the error message 'error, driver removed, please try again'

my main OS is windows 10 pro

and i'm not sure if my USB is showing in my virtualbox, it says generic mass storage im assuming thats my USB since there are no other options.

The Plop Boot Manager 5.x USB driver works only in USB 1.1 mode in VirtualBox.

I tried also setting it as 1.0 but it still says 'device not found'
