And if the OS is not compatible can it damage the device? What about charging the battery.Xp and other operating systems prefer that the driver be present when it sees a device for the first time. Although Microsoft has a pretty deep set of drivers, some are not totally compatible with every device for that make and type. Installing the software first reduces the probability you will have problems.
Do you need the software install on the computer to charge the device?You can use the USB port to charge your device, assuming you leave your system on long enough to charge it. Running the computer just to charge your device would be a waste of electricity unless it's the only way to recharge the device.
If you plan to use a USB hub for the device's connection to the computer, make sure it has an external power source. A USB mouse or keyboard don't need power, but some other devices do. Both of my USB hubs use external power and I have had no problems connecting any device to them.
All USB devices (including keyboards and mice) require power, it's just a question of how much. Your computer provides up to 500mA of current to the USB ports. If you plug a hub in without its own power supply, the hub itself is powered from your computer's bus. Everything else you plug into that will then draw power from that same source. It can add up fast and eventually be more than the computer's port is designed to supply. If the hub has its own "wall wart" power supply, the devices on it will then draw from that rather than the computer.why is this a problem?
