I am developing a simple application for which I am using a beagle board (running a linux kernel) and the TMP006EVM along with the USBDIG interface which comes as a part of it. My question is the driver which comes with the board is solely for windows. How do I communicate with this device on a linux machine. Do I have to write my own device drivers or are there some drivers already out there which will do the job for me?
We only provide official support for the Windows OS. If you wish to communicate with the TMP006 in Linux you will have to write your own software.

It is fine if I have to write my own software.But would I have to write the drivers too or only the front end gui. All I am interested is getting the data into a text file. Not a specfic front end GUI. I am using a beagle board for this project and would like to stay as far away from device drivers as possible. Are there any alternatives for me?
The current system uses the Human Interface Driver (HID) which is built into Windows, so I believe you'd need your own driver in Linux to handle the USB communication. You should contact Joe Desbonnet, a community member who has done some work on this and I believe has a working driver.
Here is a thread discussing this same topic: http://e2e.ti.com/support/other_analog/temperature_sensors/f/243/t/117449.aspx#417287
Would using LibUSb(http://libusb.sourceforge.net/api-1.0/) be a good approach?
This API seems like a good start. Have you contacted Joe Desbonnet?
Yes I did. He told me he stuck to the i2c approach.Is there any protocol documentation for how the TMP006 driver is written as I am not able to figure out much using SnoopyPro.
The USB development for our EVMs was done quite a few years ago by an outside contractor, and we don't have any documentation on it. I've attached the .dll files if that is any help.
Okay. I guess I will simply remove the USB-DIG interface and use i2c as suggested by Joe Desbonnet. Thanks for the help anyway.
