Body
In order to sample information from any sensor, you will need an intermediary. The Arduino uses an FTDI chip to convert UART (Serial) to USB. When you read data over this connection, you are reading it over the Serial over USB interface. My recommendation is to stick with using the Arduino or other micro controller. If you are really bent on reading it Directly over USB (instead of through the Serial over USB converter) you would have to implement some sort of protocol in a device that supports USB such as the <a href="http://www.ti.com/ww/en/launchpad/stellaris_head.html?DCMP=stellaris-launchpad&HQS=stellaris-launchpad" rel="nofollow">Stellaris Launchpad</a> or an <a href="http://www.atmel.com/devices/atmega32u4.aspx" rel="nofollow">Atmega32U4</a> AKA <a href="http://arduino.cc/en/Main/arduinoBoardLeonardo" rel="nofollow">Arduino Lenardo</a>. You would also have to write a driver to describe how to communicate with this USB device. Unless you were able to implement it as an already known device such as a keyboard or serial port (Yep, we went full circle there). In short, there's no already made chip that converts Analog (or Digital) values from a sensor into something any OS would natively understand. Since <a href="http://en.wikipedia.org/wiki/Universal_Serial_Bus" rel="nofollow">USB is a protocol</a> much like <a href="http://en.wikipedia.org/wiki/Internet_Protocol" rel="nofollow">IP</a>, you're not going to be able to use discreet devices. You're going to have to use a micro-controller with a USB stack. Again, my advice would be to pass the sensor values over USB through the existing Serial (over USB) port. This is pretty straight forward and easily reproducible without an entire Arduino.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
