WEB inverface via USB

Can I use the USB port on the arduino to connect to the Web like how you use an Ethernet shield?
I am thinking we have a USB port in the UNO already so can I plug it in my computer and see the arduino from the web? Not sure if there is an ip address in the UNO.

No. The Arduino is a USB slave. It does what it is told to do. It is not a USB master. It can not tell the PC what to do.

No, you can't. The PC can connect to a web server and pull or push information, but the web server can not connect to random PCs.

You could have a program running on the PC that acts as a go-between. It gets data from/puts data on a web server, and communicates with the Arduino via the serial port.

Thanks for the response. So much for my short cut trick. Its back to buying the Ethernet shield now.
The arduino is new to me but it sure is addictive.

Back when you could buy these things for little money http://www.amazon.co.uk/Seagate-FreeAgent-DockStar-Network-Adaptor/dp/B002SPI4UI/ref=sr_1_1?ie=UTF8&qid=1297969315&sr=8-1 they are pretty easy to hack into a fully fledged webserver that happily interfaces to an arduino via its USB. At one time they were cheaper than an arduino shield. I have one doing this : http://pluggy.is-a-geek.com/
