Hi,

I have a Windows Server 2012 r2 Host in use on a server with 4 Virtual Machines on it all running Server 2008 r2.

Im trying to Push a Phisical Drobo connected via USB to a newly built Virtual Machine however i am getting the error message that appears below:

Failed to attach the USB device DroboElite-8bay(2TB) Force [0126] to the virtual machine OLAF - Media/Diploma New.

USB device 'DroboElite-8bay(2TB)' with UUID {44fd8e96-d771-4113-918e-c5f4473e9375} 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 {8ab7c520-2442-4b66-8d74-4ff1e195d2b6}

If anyone can help then please do? This is bugging me now however i have got until the end of next week to get it working.

Many Thanks

Follow the steps below. If there is a failure, please state which step failed:

1. Make sure that the Extension Pack is installed. The same version as VirtualBox.
2. Create a USB filter in your guest settings while the device is plugged in the host. Delete all values except VendorID and ProductID.
3. Unplug the device.
4. Start your guest (the one that you applied the filter to). Let it start completely. Log in if you have to.
5. Plug your device. The filter should capture it and pass control to your guest.
6. If the device shows up in your host and is not captured by the filter, either the filter is incorrect, or there might be a problem with your filter installation.
7. If the device shows up, but as unavailable, "eject" it from your host, but leave it plugged in. It should show up as available.
8. Are you by any chance using a USB 3.0 port?
9. Is the VirtualBox USB Driver installed in your host?
10. Check out these two Windows-specific ways to troubleshoot potential driver installation issues:
    1. USB not working
    2. SOLVED: Failed to access the USB subsystem on Windows 7 host
11. Try your favorite search engine. It can work miracles most of the time.
