My tower case windows computer is about 4 feet from my desktop workspace. How can I have easy access to a USB connection?

I would recommend you try it with different cable. This is because you have tried different USB hub and the problem still persists.
Other possible solution provided below. However, this is if you want to connect your USB devices that are 30 meters apaart (approx. 98 feet).
Having a good quality cable might help. Amazon has Belkin 10 feet USB 2.0 cable for $10.50 + shipping

I really need to put a USB device more than 30 meters away from my PC. What should I do?
Build a USB bridge that acts as a USB device on one side and has a USB host controller at the other end. Use a long-haul signaling protocol like Ethernet or RS-485 in the middle. Using cables or short-haul fiber, you can get ranges upwards of a kilometer, though there's no reason why the long-haul link in the middle of the bridge couldn't be a pair of radio transceivers or satellite modems.
Embedded host solutions capable of doing this already exist. Also, two PCs connected via USB Ethernet adapters are essentially a slave/slave version of this master/slave bridge.

USB 2.0 is supposed to be good to 5 meters length should not be the problem here.
If your hubs are cheap, make sure they are really 2.0. They may be downgrading the devices you are plugging in. I don't like hubs for hard drives, they tend to slow down transfers.
This may also be a problem with your tower. Do the connections work if plugged directly in and not through an extension or hub?

Not only that but if you plug in USB 1 devices you might be affecting the speed of everything else because hubs run at the speed of the slowest device.

You may want to have a good look at the USB devices that are giving you trouble, especially if they are older than a year or two. I've had a series of enclosures that just didn't do well on various hubs, but did just fine connected directly, even over long (8 foot) extensions. It has something to do with the embedded USB controller and how it manages AC and the USB connection. and the older the device was, the flakier it made my entire USB chain. Devices that previous worked flawlessly started acting up, and don't get me started with all the havoc it caused on my Linux system!

I have had tons of problems with power issues on front ports.

"However, you may also want to consider a software IRQ / DMA conflict in Windows or that something is physically wrong with the USB connector inside of your computer."
This is what I would be looking at.
I agree with this answer.
Most likely the extension cables that you've been using are bad.
However, you may also want to consider a software IRQ / DMA conflict in Windows or that something is physically wrong with the USB connector inside of your computer.
I personally use a 16ft USB cable every day. I have never had a problem with the length in any OS (windows, mac, linux) or with any device (external hard drive, printer, scanner, etc)
