Windows VirtualBox failed to attach USB device to Linux Guest


I have Windows 7 64bit Host system, and I am using VirtualBox 4.1.18 (r78361).

I have an Arch Linux Guest OS.

I have installed VirtualBox Extension Pack (to enable USB2 support) and added my USB device filter to VM.
I have also installed the Guest Additions provided by Arch: virtualbox-archlinux-additions (but I have no idea whether it's actually needed for my environment).

I can see my USB device from VirtualBox Devices menu.

Whenever I am trying to access it, I end up with:

Failed to attach the USB device Kingston DT 100 G2 [0100] to the virtual machine Archlinux.

USB device 'Kingston DT 100 G2' with UUID {a836ec33-0f41-4ca7-a31d-09cceaf5d173} is busy with a previous request. Please try again later.

Result Code:    E_INVALIDARG (0x80070057)
Component:      HostUSBDevice
Interface:      IHostUSBDevice {173b4b44-d268-4334-a00d-b6521c9a740a}
Callee:         IConsole {1968b7d3-e3bf-4ceb-99e0-cb7c913317bb}

From what I have googled, most guides shows how to solve this the other way around - Linux Host to Windows Guest.

How do I resolve this?


I have tried to Eject (virtually, not physically) the device from my Windows Host system and then try to access the Device from Guest. Same error.

It looks like VBox has some problems with USB3 hubs, and so, plugging my USB key into an USB2 slot did everything. See here.

This is years old and there is still a problem with USB 3.0 in VirtualBox.

I'm running an up-to-date Ubuntu 20.04 host, Virtualbox 6.1.10_Ubuntu r138449 (most recent in Ubuntu repos) with a Windows 7 guest. My computer only has USB 3.0 ports. My external USB 3.0 hard drive fails to attach to the guest.

In my urgent case, I plugged a USB 2.0 hub into the computer, and the USB 3.0 HDD into that hub. It works, but at USB 2.0 speeds :)

Also, with any Linux host, make sure the user running VirtualBox is in the "vboxusers" group.
