It seems like hotplug et al is getting cleverer and cleverer. But I don’t want it to be…
I have Win XP running in VirtualBox on openSUSE 21.1 and when I plug in my mobile phone it no longer appears in the ‘Devices’ menu in VirtualBox. Under 11.4 it did. I suspect the problem is that linux is capturing it and not allowing the passthrough to work (other USB devices are fine and I already have a filter set up in Virtualbox).
Dmesg now gives:

So presumably the various drivers are not letting Vbox access the phone. I don’t know much about hutplug and usb, but I see two potential reasons, one that Virtualbox simply no longer has access rights to the devices (owner is changed) or two, that drivers prevent VirtualBox from accessing the devices.
Can I stop linux usb from doing this? Is there a simple rule I can write with the device ID to prevent drivers grabbing a device?
