Background:
I have a Windows machine connected to 4 (similar) devices using USB 3.0.
This machine is running scripts which test the connected devices (as part of a big lab).
I thought it might be easier to run 4 VMs, each connected to one device (this will make automation life much easier).
Guests should be Windows 7.
Since I only have Windows 7 machines I'm currently using it for the Host as well.
So far:
I was able to create the 4 VMs and define filters to connect (successfully) each VM to one device.
I'm able to communicate from each of the VM with the appropriate device.
My problem:
During test initialization, the script sends a restart command to the device which is then disconnected from the machine.
When the device turned on:
1) it's not recognized anymore by the VM.
2) The Host is displaying Cypress USB driver (instead of VirtualBox Driver).
3) Trying to connect the VM explicitly fails with 'USB device 1.0.9 FX3 with UUID {XXX} is busy with a previous request. Please try again later'.
4) As far as I can see, the device is available (to the VM) again only after restarting the host.
More info:
Host is located inside a data center, I'm using Remote Desktop.
Host and Guests are not connected to the internet, all drivers must be installed manually.
As part of the host configuration: 'Renesas Electronics USB 3.0 Root Hub' is installed.
My questions:
1) Any clue or suggestion for identifying the reason for this failure?
2) In many guides describing how to solve USB issues with VB, I have been asked to plug out (and then in) the USB device, is there a way to mimic this using Remote Desktop?
3) Before trying this on Lab's machine, I tested on my desktop, I saw the same problem and tried several methods to solve it, nothing helped but somehow, when I tried to debug the process, the problem disappeared.
I know it didn't disappeared because of the debugging, is there a chance Windows installed a new driver without notifying me?
Any help will be appreciated.
Thanks for reading this.
