Arduino Uno R3 problems with USB

Yesterday I could suddenly not upload code on the Arduino. This is the verbose output: (just upgraded from 1.0.2 to 1.0.3 to see if that fixed it )

Using Port : \.\COM7

Using Programmer : arduino

Overriding Baud Rate : 115200

avrdude: Send: 0 [30] [20]

avrdude: Send: 0 [30] [20]

avrdude: Send: 0 [30] [20]

avrdude: Recv: 0 [30]

avrdude: stk500_getsync(): not in sync: resp=0x30

avrdude done. Thank you.

it says Overriding Baud Rate 115200, but in Device Manager it is set to 9600.

Anyone have any ideas?

I tried different ports and cables. Same everywhere.

Edit: Tried same cable/usb port on a Mega, worked fine. Arduino.exe says that the Uno is connected on the correct serial port.

Ah i fixed it. I was working on getting my Uno and Mega to talk over RX/TX. Apparently the Uno doesn’t like that, but the Mega didn’t mind as long as I was using RX1/2/3 ports… I had to disconnect RX/TX wires on Uno and then it Worked. Should have known, I actually read that yesterday!

Marking as solved and leaving it here in case other people has this issue.
