1. choose system> Management> user and group> Management Group (m ): "usbusers" is added to the group. (Note that this section will be used to set the usb fs step under "group awareness ), and users who use vitualbox will be checked.

2. Start the terminal and run the following command:

sudo gedit /etc/udev/rules.d/40-permissions.rules

Find:

# USB devices (usbfs replacement)

Ubuntu 7.10 USB FS

In Ubuntu 7.10, when usb fs is configured, the following error occurs in virtualbox:

Cocould not load the host USB proxy service (verr_file_not_found). The service might be not installed on the host computer.
 
Result:
Zero X 80004005
Ingredients:
Host
Interface:
Ihost {81729c26-1aec-46f5-b7c0-cc7364738fdb}
Called end:
Imachine {31f7169f-14da-4c55-8cb6-a3665186e35e}

In order to fix this problem, I rummaged through it and found the following methods:

Start the terminal and run the following command:

sudo gedit /etc/init.d/mountdevsubfs.sh

After opening the instance, find:

#
# Magic to make /proc/bus/usb work
#
#mkdir -p /dev/bus/usb/.usbfs
#domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
#ln -s .usbfs/devices /dev/bus/usb/devices
#mount --rbind /dev/bus/usb /proc/bus/usb

Remove the # Of the last four rows as follows:

#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
domount usbfs "" /dev/bus/usb/.usbfs -obusmode=0700,devmode=0600,listmode=0644
ln -s .usbfs/devices /dev/bus/usb/devices
mount --rbind /dev/bus/usb /proc/bus/usb

Save the statement and then merge the rows:

sudo /etc/init.d/mountdevsubfs.sh start

Run the following command:

sudo gedit /etc/fstab

Add the following lines at the end of the sequence:

none /proc/bus/usb usbfs devgid=1002,devmode=664 0 0

Note that the devgid is the "Group Awareness" in the preceding permission restriction step 」.

Try again laterOrRun the following command ):

mount /proc/bus/usb

It will not cause any further warning, and the USB flash drive can be used properly.
