Using usb hub's on your laptop's
 

If you are using a USB hub and it is self powered
and you are having problems with hoster or any other programs

this need's to be replaced with a powered one
what is happing is the USB rescores are not enough to handle the added
plugs that the hub is giving you. it is drawing more power then the unit has
and is causing the hard drive or the sound card or the mouse
what every you are using to stop working for a sec or two

and in the case of the sound card it will cause the program to crash

so if you plane to use a hub buy a powered one
