I've created a wireless PCB that connects an XBee Zigbee module to the UNO32. There is a set of jumpers that selects whether the module connects to UART2 or UART1 on the UNO32. I believe the MPIDE leverages the Microchip USB HID bootloader? Is there an easy way to upload a compiled sketch when directly connected to UART1 or would I need to use a different bootloader?
Thanks in advance for any assistance.

It's possible with the new USB bootloader optons. Also, the UNO32 has 2 uarts. If you use pins I think 39, 40 you would be ok.

From my understanding the old one uploads sketches via the USB connection, FTDI USB to serial, which is connected to UART1. What's new in the USB bootloader? It sounds like the new one might support uploading sketches directly on UART2 (pins 39 & 40)? If so, then this will be great. I'll have to investigate the new USB bootloader in detail.
