I just got my V2 yesterday and like it very much. Read about the BenF enhancements, but am having a problem updating the firmware.
I’m running Windows 7 and have installed the DfuSE demo software. When I boot the unit with ‘down’ depressed I see the two messages
“Please Connect to the USB Host” and
“DS0201 Device Firmware Upgrade Ver 2.0”
But when I then plug the USB cable into the PC I hear the USB device beep twice, but then nothing happens. No “Firmware Upgrading… Please Wait” messages appear.
I’ve tried this many times with identical results. What am I overlooking? Or could this be a hardware/driver issue?
The Nano seems to be performing all of its other operations OK. The only problem is this upgrading procedure.
