Yes, it's clearly not xgaming's fault. I'm sure they're just as frustrated as anyone else.

USB in fact means universal serial bus. The whole idea behind the standard was to eliminate compatibility problems and make it so that one port could accommodate a whole range of devices, from printers to mice to external hard drives--you name it. There's really no good excuse to make a game port unique to a system, unless (as you rightly suggest) it's purely in the interest of the manufacturer, who can then apply patent pressure to get more money. They see as just as another profit stream (along with licensing all software for their console, etc.) I guess this works out fine for console makers, but it hurt proprietary computer makers. Let's not even get into the drivers hell associated with printers even right up to this day. It baffles me that I have to go through torment to get a brand new printer to work with my Mac and PC, and I shiver when I think about what Linux folks must have to go through.

What makes even less sense to me are proprietary power supplies and ports. I mean, what the hell? Are they afraid someone else is going to try to make a better power supply--or are they really making that much money from selling replacement power supplies? I'm always enraged when I buy a device and find that it has some wacko power supply and hookups that can't be replaced with an off-the-shelf part.
