fix virtual box usb problem on fedora

error message:

Failed to access the USB subsystem.

Could not load the Host USB Proxy Service (VERR_FILE_NOT_FOUND). The service might be not installed on the host computer.

Result Code:
0x80004005
Component:

Callee:
IMachine {31f7169f-14da-4c55-8cb6-a3665186e35e}


solution:

1- obtain GID of vboxusers
# cat /etc/group |grep vboxusers |awk -F : '{print $3}'
501
 
2- create directory
# mkdir /vbusbf

3- add the following line to file /etc/fstab
none /vbusbf usbfs rw.devgid=501,devmode=664 0 0        (the number 501 need to be changed accordingly to step 1)
 
4- add your current log in user (ex. my accout is dara ) to vboxusers
#usermod -a -G vboxusers username  -- (ex, usermod -a -G vboxusers dara)
 
 
5- Reboot your PCs
