my computer is all the way up on the second floor, while my xbox 360 console is in my basement, would it be possible to run all the cables to their max length and plug easyCAP in, then plug that into 10 ft usb extension cables the rest of the way, or not, or would it lose quality?

Ahoy!

In essence, you should be able to, however it's difficult to judge, since USB should have a fairly reliable throughput, regardless of length - however, after reading through, here's some info which may be useful to you...

taken from http://en.wikipedia.org/wiki/USB#Maximum_useful_distance

Maximum useful distance

USB1.1 maximum cable length is 3m[17]. USB2.0 maximum cable length is 5m. Maximum hubs connected in series is 5. Maximum devices connected in total is 127.

Although a single cable is limited to 5 meters, the USB2.0 specification permits up to five USB hubs in a long chain of cables and hubs. This allows for a maximum distance of 30 meters between host and device, using six 5-meter cables and five hubs. In actual use, since some USB devices have built-in cables for connecting to the hub, the maximum achievable distance is 25 meters + the length of the device's cable.

USB 3.0 does not define cable assembly lengths, except that it can be of any length as long as it meets all the requirements defined in the specification. However, electronicdesign.com estimated cables will be limited to 3 m at top speed.[18]

Since USB provides power for devices connected to the bus, a special type of USB extender cable was created, consisting of a miniature one-port USB hub molded onto one end of a 5-meter cable. These mini-hubs are fully self-contained within the cable, requiring no separate bulky hub device and no external power. They are as simple to use as plugging cables together, with each hub drawing power through all the previous single-port hubs in the chain. Because bus power is limited, the most practical arrangement consists of four single-port hub extender cables, one plain 5 meter cable and, at the very end, a powered multiport hub to support multiple USB devices.

-----
Sounds like it is possible, but generally speaking not very cheap - I use my laptop for recording, since I was never very game to try and run a very long usb cable....I think the problem with a really long one cable is the use of power all along it (since USB holds the electricity charge throughout the cable) -

Hope this helps!

Kind Regards,
Fenberry
