Hi Gents,
I got my USB smartcard running in the guest system (Windows 7) as described in FAQ / tutorials.
But when I reboot the guest the usb device is unavailable. When I try to connect the USB via VB statusbar I get the error message: "Failed to attach the USB device xxx to virtual machine yyy".
What helps is re-plugin the device. But that's annoying to do every time.
I tried with USB 1, USB 2 and USB 3 - nothing worked so far.
I there a way to tell the MAC to not attach the device to macOS and always keep it available to be used in the VM? I think that's the reason for this issue.
regard
host:
iMac Pro High Sierra
VB 5.2.4r119785 + extension pack
guest:
Win 7 32-bit + guest plugin + Intel USB 3 driver

No. Only a filter will capture the device before it reaches another layer of software, but still the computer knows about the device.Ragnar666 wrote:I there a way to tell the MAC to not attach the device to macOS and always keep it available to be used in the VM?
Please read the following thread: USB basics and troubleshooting, all of the posts. If you still have a problem after reading through the whole thing, please follow the advice of the last post, #8: Asking for help.
PS. For future reference, "current version", "latest version", "previous version" don't (generally speaking) provide accurate information. In a couple of months the "current" will definitely be different. It's better if you use the complete version numbers (including the build numbers) to identify software.

Re: USB Device not usable after reboot of guest
Thanks for your reply. I've corrected the version.
Yes, I read the tutorial several times.
There are 4 device categories:
Currently it seems that my device belongs to the category "un-ejactable": "You have to unplug them and use a USB filter. The on-the-fly option doesn't work, simply because you cannot release them from your host."
But maybe there's a way to eject the device in MacOS: "You have to eject them first to be able to use them with the on-the-fly option." It's much easier to issue a command to eject the device than to physically unplug and replug the device.
Any idea?

Re: USB Device not usable after reboot of guest
That's it I'm afraid. You could use that with a hard disk (probably). You can't use this trick with a smart card. Otherwise, it would have been in the FAQ.
