You either need a USB cable or a Bluetooth (BT) dongle.  Dongle just
refers to the form factor of the adapter.  Bluetooth, IMO is much
easier.  The wireless notebook your son has is not the same type of
wireless.  The two won't share without a BT adapter.

I purchased a Blue-Gene BT-303U USB1.1 Bluetooth USB Adaptor from
NewEgg.com.  Currently they are running $20 w/$3.99 shipping.

You can spend much more and you can find them for less.  All I know is
this one works with the V551.

Installation was easy following the instructions.  If your son or
daughter has upgraded to XP Service Pack 2 (SP2) and have problems, I
suggest running the program from the following link.

If the machine has more than one USB port, you may need to re-run this
fix for each port you plug into.  But once you fix it, it should stay
fixed.  That's how it worked for me and mine.

Once the BT hardware and drivers are installed you need to pair the PC
and the phone.

On the V551 press the top middle button. Select
SETTINGS >> CONNECTION >> BLUETOOTH LINK >> SETUP  
If you want to change the name of the phone as it appears to other
devices, this is where you do that.  By default it will be "Motorola
Phone".  Leave the phone on this menu for the moment.

On the computer, with the BT dongle plugged in, click on My Bluetooth
Places.  It may be on the desktop but is also available from My
Computer.  The logo is a vertical blue oval with a funky B that looks
something like this

Select ADD A BLUETOOTH DEVICE  from bluetooth tasks section on the
left.  A wizard should open.  Now tell the phone to be "Discoverable".
From the phones bluetooth setup menu, select FIND ME.  You now have 60
seconds to run the Add a Bluetooth Device wizard.  Click the NEXT
button in the wizard.  It will search and find the phone.  When it
does, select the phone it found and click NEXT.  

Enter a PIN code.  It can be anything you want. 1234 will work.  Click
INITIATE PAIRING.  

On the phone the screen should now be asking if you want to bond with
the computer.  Choose yes.  Enter the pin you chose.  

You will see some successful bla bla bla and then Blue Tooth Service
Selection.  By default, everything is checked.  Make sure OBEX File
Transfer is checked. Click FINISHED.

Back to My Bluetooth Places.  Your phone should now show in that
window.  Click on it to open (or double click depending how your PC is
set up).  Open OBEX File Transfer on (your phone's name here)

Now all you need is basic drag and drop window skills.  There will be
3 folders.  Audio, these are ringtones.  MP3s and MIDIs work.  Video,
these are the videos taken with the phone.  Apple's Quicktime will
play them and is available for free from
http://www.apple.com/quicktime/download/win.html
And finally Picture, this is where the pictures you were after the
whole time.

Hope this helps you and maybe someone else who was wondering the same
thing.  Good Luck
