USB 1.0 vs 2.0

Been using the same cable to connect my USB 2.0 device to PCs using USB 1.1 and USB 2.0

If your device is USB 2.0 enabled (that means your camera/ USB key/ External USB HDD) and you connect it to a PC with a USB 2.0 socket it will use the higher speed of transfer approx 480MB (your mileage may vary).

If your device is USB 2.0 enabled (that means your camera/ USB key/ External USB HDD) and you connect it to a PC with a USB 1.1 socket it will default back to the slower speed since USB 2.0 is backwards compatible

The cable is not that important, basically any USB cable should work (obviously a 50 cent cable that you found lying on the sidewalk doesn't count) cables with gold platin...etc might be able to squeeze a little more data but i dont think they are worth the extra $$$

The main things affecting the version of USB you are using are:

1- The device you want to connect
2- The port on the back of you computer (or the add on PCI or PCMCIA card you bought extra)

device USB 2.0 + port USB 2.0 + cable = USB 2.0
device USB 2.0 + port USB 2.0 + USB 2.0 HUB + cables = USB 2.0

anything else with anything that says USB 1.1 in the middle equals USB 1.1 connectivity
