I cannot connect my Uno to Windows 8 no matter what I try.
No matter what I do, I get the same "avrdude.exe: stk500_getsync(): not in sync: resp=0x00 error". No blinking tx or rx lights on the arduino.
I've tried the regular method of installing the drivers, but when I open the folder where the rivers are contained, it is empty as far as the browser is concerned. Nada. Just a folder with an FTDI subfolder.
I've tried to download the Arduino enhanced release software that is suppose to handle Windows 8. Nothing. Nada.
Ive tried installing it as a modem. Nothing.
I've changed the security setting to allow unsigned drivers. Nothing.
I have no idea how to proceed. Is there any solution for Windows 8 that actually works?
You don't have another Arduino you could try, do you? I wouldn't focus on Windows 8, it hasn't caused any problems on two machines here, and that includes running about 5 or 6 Arduino releases back. I might even say it's an improvement over Windows 7.
Well, after reflashing the 16U2, fiddling with the drivers a dozen more times, and trying everything else I could think of, I'm concluding that either the board is dead, or none of my computers will ever work with arduino.
Oh well.
If you get the same error, try to install the drivers, then reflash the 16U2, then give up. If those don't work, It's trashed.
