How to use USB in Sun xVM Virtualbox?

In this article, I documented and enumerated the steps on how to make your USB working on a windows XP inside Virtual box. This article is help ubuntu Hardy and Gutsy user who are having problems on using there USB's on there virtual machine.

Step 1

• During installation of VB, it creates a group named as "vboxusers". Add yourself to the group.

Step 2

• Create a group named "usbusers" and put yourself in it.

Step 3

• Now uncomment the 4 lines below 'Magic to make /proc/bus/usb work' in mountdevsubfs.sh , they will be commented out by default) so it looks like the following:

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

#
# 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


Step 4

• Modify the rules in file “/etc/udev/rules.d/40-permissions.rules” for Gutsy, and “/etc/udev/rules.d/40-basic-permissions.rules” for Hardy:

Change the lines :

From:

# USB devices (usbfs replacement)
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664"
SUBSYSTEM=="usb_device", MODE="0664"

To :

# USB devices (usbfs replacement)
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GROUP="usbusers", MODE="0664"
SUBSYSTEM=="usb_device", MODE="0664"


Step 5

• add this line:

none /proc/bus/usb usbfs devgid=120,devmode=664 0 0

• to your /etc/fstab file. Make sure that the "120" is your vboxusers group (use your own number). To find out your number run command "cat /etc/group | grep vboxusers".

Get paid to surf ads using bux.to

bux.to seems to be quite a popular paid-to-surf ads program. The process requires you to click a link and view a website for 30 seconds to earn money. You can earn even more by referring friends. You’ll get paid $0.01 for each website you personally view and $0.01 for each website your referrals view. Payment requests can be made every day and are processed through PayPal. The minimum payout is $10.00.

What makes it even more interesting is the fact that you can buy various referral packages that can enable you to jump start your earning capability. All the referrals come with a ‘replacement guarantee’.

There are several forums where bux.to users have shown proof of payment.

An example of potential earnings for 100 active referrals (based on averages):

• 100 referrals click 10 ads per day = $10.00
• Your daily earnings = $10.00
• Your weekly earnings = $70.00
• Your monthly earnings = $300.00

Well, if you can spare 10 minutes each day on bux.to you may earn money from it, as described above. It all depends on how many referrals you can bring into your network.

What do you think? Will such programs be successful in the long run? Can users really earn significant amount from such websites?
