This is at least the 4th time you have posted about the same thing. Please stay with one thread.
Speed Without going into any technical detail, USB is broken up into three speed groups; Low Speed USB1(1.5Mbps), Full Speed USB1.1 (12Mbps), and Hi-Speed USB2 (480Mbps) basically how fast data is tramsferedfrom the device from/to the PC.
Look in contol panel device manager at the USB controllers if you see one with the word "Enhanced" then you have USB2.
Your problem is probably down to the fact that the laptop cannot supply sufficent power through the USB ports (5V at 500mA)to support your device.
Certain USB devices draw power from the computer via the connection. It may be that your laptop cannot supply enough current to power the device. It has nothing to do with the processing/graphics power of the laptop but a simple power supply (as in volts and amps) problem. If you have other usb devices connected to the laptop it may help to remove them.
With most laptops you can fit a PCMCIA/Cardbus USB card which normally gives 2 or more USB 2.0 ports and more importantly provide a power adapter either to a standard powered 3 pin mains socket or an adapter that draws power from the PS/2 keyboard port.
