USB access from a Linux guest

[robertb]

I am having many problems trying to access a USB drive from VB running Linux (Linux Mint 64-bit, Debian Edition, in particular). I have one of two problems:

• 1) When I select the USB drive from the Devices->USB, it never gets checkmarked (in the checkbox) and the USB driver is not accessible -- the kernel doesn't register the device.
• 2) I get an error:

  Code: Select all

   Failed to attach the USB device Toshiba External USB HDD [0103] to the virtual machine mint
   USB device "Toshiba External USB HDD" with UUID 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 {db7ab4ca-2a3f-4183-9243-c1208da92392}

Selecting another USB device seems to work. For example, a "Intel(R) Corporation Intel(R) Centrino(R) Advanced N + WiMAX 6250" gets a checkmark and is accessible in the VM.

Things I've tried without success:

• Using another Linux release (Finnix, in my case).
• Downgrading to 4.2.8 from 4.2.12.
• Plugging the USB drive only after VM has been booted completely.
• Plugging in the USB drive before the VM boots.
• Plugging and unplugging the USB drive while the VM is up.
• Adding a Settings->USB->USB filter to mount this drive. (This always causes the "busy with a previous request" error.)
• Adding a blank USB filter.
• Removing "upper filter" from the registry via regedit
• Reinstalling the Oracle VM VirtualBox Extension Pack.
• Turning on EHCI Controller.
• Turning off EHCI Controller.
• Plugging into different USB ports.
• Adding the user to the vboxusers group. (This group doesn't exist in the guest; besides, I'm just looking at /var/log/messages to see if the kernel registers the USB device so that doesn't matter in this case.)

I should also note that this machine has some unknowable security software installed on it. I don't know if this is interfering with VBox or not.

Any other suggestions that I should try?

Ah, that's a better search than I tried . I'll look through the billion posts and see if there's something I haven't tried...
