Belkin Seven Port Powered USB Hub in Orange, CA

I have a bit of old technology here. A Belkin seven port USB hub that I guess at the time was meant to be like a flex technology where you could adapt it to your needs. The model number is F5U100. As you can see by the photos its rather large compared to today's USB hubs. The top three USB ports are modules that pull out and you can replace them with modules that have more USB slots in them. Of course the issue now would be where can you find those modules anymore? That's why this is selling cheap. This is a link to the Belkin support site that has the user manual
