Most new motherboards come with 4 USB ports.
Now when you unplug the printer and plug it in again in a different port, it treats it as a new device. Plus you can dasiy chain 127 devices out of one port. So you can litter-ally install that printer 4x127 times on your computer. Printers and scanners preboot before the O/S loads.
So if you forget to read the instructions on installing an HP printer scanner, you have to call me in order to get it running. You have installed it seven different ways and it is not going to run.
The first thing to remember when you install a scanner or printer, rule one. is to not hook it up, install the software first and then when it tells you, hook it up. The bad news here is that when you plug it into another port, you have just violated rule one. It gets worse, now the system thinks that there are two printers to load before the O/S loads and you get the find new hardware routine.
My suggestion is this; pick a USB port for the printer and use it only for that. Buy a USB hub with a power supply assist (the basic amperage draw of a motherboard is 500 mili amps per USB port max. Exced that and you run the risk of blowing the power supply)
and use that for the other devices, and pay particular attention as to the port you use for each device.
USB is too stupid to realize that it is the same device, hope this is of some help
