I having trouble with my arduino uno being recognized by my Windows7 computer. (and i have tried it on all 4 of my computers) It comes up as unknown device in device manager instead of arduino uno. Every time I try to install the driver it fails. Plz help
Thanks,

Make sure your "drivers" folder in your Arduino installation contains a Uno R3 inf file.  It is included in 1.0.

What does "still cant program it" mean?  Is there an error message?  Does the serial port show up in the IDE?

Do you have the right board selected in the Tools menu?  Did you check the troubleshooting guide?  http://arduino.cc/en/Guide/Troubleshooting#upload

yep and i checked everything in the troubleshoot page and it still doesn't work

I just had the same problem with my Uno R3... did you specify the install location for the driver? I kept choosing the wrong Unknown Device but now mine works. I just followed the install page at http://arduino.cc/en/Guide/Windows#toc4

I have a HP G60t (shame...) with Win7 SP1 64 bit.

I was having the same issue. Win 7 doesn't have the drives for it so you will need to install them.

The Uno doesn't have an FTDI chip, so you don;t need FTDI drivers... the drivers are in the Drivers subfolder of the arduino-1.0. folder. You need to manually install them.

I got the driver installed and it says arduino uno r3 in device manager but i still can upload any sketches to it with arduino's program
