I am using the RX and TX pins on the Arduino Uno and moving the USB connection to a different location away from the microcontroller instead of the plugging the USB directly into the microcontroller. I have the the serial to USB adapter from Arduino and have hooked it up this way:
I get this message when I try to upload:
Avrdude: stk500_getsync(): not in sync: resp= 0x00.
and I get this message when I hold shift and try to upload:
Avrdude: usbdev_open(): did not find any USB device "USB"
Either way the program says "Done Uploading" but the new program has not actually been uploaded to the board. Any help on how to resolve the issue?
