Powerhouse heeft een artikel over USB in elkaar gedraaid:
Have you ever tried installing a new modem, only to have your system lock up when you turned it back on. Or even worse, you load Windows just fine, but when you try to use your new modem suddenly your mouse no longer works, or the dreaded blue screen appears.
What about hooking up that new parallel port pass-thru cable so you can use that new removable hard drive. The drive seems to work fine, but suddenly you no longer have access to your printer.
How about those game ports, they use up precious CPU cycles, you can't hook up more than one type of joystick at the same time (unless your using the joyswitch or Y-cables), and some joysticks have problems working correctly with various game ports. Not only that, but some of the newest Force Feedback game controllers require both the game port and serial port to work correctly. All of these problems have plagued PC users for years and it's just now starting to change.
