[aur-general] Virtualbox quite suddenly can't access shared folder anymore

[Ralf Mardorf]

PS:

This is the file from the AUR:

$ cat /lib/udev/rules.d/10-vboxdrv.rules 
KERNEL=="vboxdrv", NAME="vboxdrv", OWNER="root", GROUP="root", MODE="0600"
SUBSYSTEM=="usb_device", ACTION=="add", RUN="VBoxCreateUSBNode.sh $major $minor $attr{bDeviceClass}"
SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", RUN="VBoxCreateUSBNode.sh $major $minor $attr{bDeviceClass}"
SUBSYSTEM=="usb_device", ACTION=="remove", RUN="VBoxCreateUSBNode.sh --remove $major $minor"
SUBSYSTEM=="usb", ACTION=="remove", ENV{DEVTYPE}=="usb_device", RUN="VBoxCreateUSBNode.sh --remove $major $minor"

This is how '60-vboxdrv.rules' from
https://www.archlinux.org/packages/community/x86_64/virtualbox/
looks like:

KERNEL=="vboxdrv", NAME="vboxdrv", OWNER="root", GROUP="root", MODE="0600"
KERNEL=="vboxdrvu", NAME="vboxdrvu", OWNER="root", GROUP="root", MODE="0666"
KERNEL=="vboxnetctl", NAME="vboxnetctl", OWNER="root", GROUP="root", MODE="0600"

SUBSYSTEM=="usb_device", ACTION=="add", RUN+="/usr/share/virtualbox/VBoxCreateUSBNode.sh $major $minor $attr{bDeviceClass} vboxusers"
SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", RUN+="/usr/share/virtualbox/VBoxCreateUSBNode.sh $major $minor $attr{bDeviceClass} vboxusers"
SUBSYSTEM=="usb_device", ACTION=="remove", RUN+="/usr/share/virtualbox/VBoxCreateUSBNode.sh --remove $major $minor"
SUBSYSTEM=="usb", ACTION=="remove", ENV{DEVTYPE}=="usb_device", RUN+="/usr/share/virtualbox/VBoxCreateUSBNode.sh --remove $major $minor"

However using the AUR build with the rules file from community, the result is that USB is missing...

$ ls -hAld /dev/vbox*
crw------- 1 root root 10, 56 Jul 27 14:48 /dev/vboxdrv
crw-rw-rw- 1 root root 10, 55 Jul 27 14:48 /dev/vboxdrvu
crw------- 1 root root 10, 54 Jul 27 14:48 /dev/vboxnetctl

...and I got rid of
"Failed to open "/dev/vboxdrvu", errno=13, rc=VERR_VM_DRIVER_NOT_ACCESSIBLE",
but the Windows 7 guest still crashes, if I try to access the shared folder.
