Whoo hoo!

Now, (without using the Pickit2)

You have run the HID Bootloader executable from microchip http://www.cpustick.com/downloads/HIDBootLoader.exe , and see if it can find your UBW32. If the Microchip Bootloader sees your hardware, select the first firmware I sent you in post#463. This one: StickOS for Microchip PIC32MX4-F512L UBW32 Board Bootloader (v1.80) (.HEX, UBW32 HID bootloader image) with the long name, and try to load it into the device, using the bootloader.

If it loads, you may have to unplug it, then plug it back in, to see if it takes. Then watch your device manager, to see if you get any new serial ports.
