Hi,
So I have this PC previously installed with FreeDuino and FTDI drivers. Now when I connect my Uno with my PC, it can't recognize the board. I tried to update the driver manually (tried both from the FTDI folder and the driver folder which has AruinoUno.inf) but it still doesn't work. It says it's already the latest version and doesn't update anything. I tried to uninstall the FreeDuino device from the device manager but it seems not the solution. Everytime I connect the FreeDuino again, the driver just automatically install itself.
I guess I need to remove the older version of FTDI drivers on PC and re-install the correct version? Any idea how I can do that?
Thanks a bunch!

Re: PC previously installed FreeDuino and now can't install Uno
The Uno doesn't have an FTDI chip. You have to install the drivers that go with the Uno (either "Arduino UNO.inf" or "Arduino UNO R3.inf" (these aren't actually drivers, they're just descriptors that say "This is a serial-port-like devices and you should use the usb serial port drivers that are already part of windows", but they still need to be installed.)

Thanks for your reply!

Mine only shows "unknown device" under "Other devices". I'm not sure if it makes a difference, but I can't install the "Arduino Uno.inf" driver from device manager. It says it's the latest driver and doesn't do anything. Is there other ways I can install the Arduino Uno files?
Thanks
I read other posts saying that your Uno board should show "Uno" under the Port (COM&LPT) in device manager.You have to install the drivers that go with the Uno (either "Arduino UNO.inf" or "Arduino UNO R3.inf"

Try to un-install any existing driver first.It says it's the latest driver and doesn't do anything.

Re: PC previously installed FreeDuino and now can't install Uno
Hi, I know it's been a while but this is still not solved. I have been using my friend's board during this time and it works totally fine on my laptop.
And I found this post:

I just tried my board again and checked the log, it's exactly like the one you mentioned:
Is it possible for me to get a replacement?

Yes, it has been a couple of months.
The symptom you describe is consistent with the 8u2 chip losing its programming. And it is typically correctable - as noted further down in the link you posted. http://forums.adafruit.com/viewtopic.ph ... 57#p122255

Hi- Thanks for the reply. Good to see it can be fixed but unfortunately I don't have a USBtinyISP...
Any other suggestions? Is there anyway I can get a replacement?
