Epson R300 Comuncation/consistency problem

Hello guys,
I've been navegating in the Net for 3 days now trying do find a solution for my problem, and I think this is the right forum

Since I've bought this printer, over 18 months ago, I've got this problem, and I think is is USB related:

1 - I Can't install it properly, when the message from epson installer asks for printer detection and I plug the USB cable with the printer ON, the installer can not detect it, and windows instals it by its own. (eventualy its installed, after playing around a lot, but I think the USB port is not properly assigned)

2 - Last time I formated and installed XP SP2, the problem got worse. I only have two USB ports in the back of the PC, one was connected to the mouse, and the other connectec to the printer. The printer never worked... Well, It did, when I removed the mouse to a standard mouse port...

3 - Even now, I have a LOT of communication failures, if I connect to the NET...it fails, If I use another program, It Fails.... and so on...

I'm not a computer expert and I'm running out of options, however, I'm pretty sure this is a USB problem.

My computer:

MB - Matsonic 9147C (don't laugh...)
Intel Pentium IV 2,4 Ghz
512 DDR Ram
Nvidea MX 400
