Is this hard to do?

Hi,
I am very new to doing my own tinkering. But I've been programming for years. For some years I've also done simple physical drivers etc.

Now I want to learn more and was thinking of a project that I would find useful in the end.

I want to build a USB monitor. In essence something like 3 (4?) USB ports. Plug device 1 into the box and then from the box to device 2,
but I'd also receive both uplink and downlink packed over yet another (or two) usb links. I was thinking of just outputting to a rs232, but I guess that is too slow.

I would love to know the degree of complexity? I understand that this might not be the best starter project, but it really isn't the first thing I will do. As long as it is feasible, I have no problem with starting with flashing leds to learn.

Any thoughts, suggestion would be appreciated.

USB programming is fairly complex from what I've seen. That being said, I doubt the arduino has any USB capabilities beyond the USB to serial chip that is used on the arduino board. The below probably has some good info.

The atmega328 on the arduino and other AVR microcontrollers can do low speed USB, but not higher speeds.

other thoughts, the threads title is very vague
