total fail on firmware upgrade for both OSX and XP

I know I must be doing something DUMB. Please point it out to me!

I have tried both the 3.0 and 3.0.1 on XP. On machine one, st demo fails to run. cRASH

On XP system 2. it never recognizes the dso nano.

On OSX,

dfu-util does currently only support DFU version 1.0

No DFU capable USB device found

The both my DSO nano and dso nano ver 2 are “DS0201 Device Firmware Upgrade Ver 2.0”

I know I have upgraded software before. This time nothing is working.

I prefer if someone has working OSX instructions.

It was the (&(()&^@#$%^ usb cable. Used a different cable and all worked perfectly on XP.
Hours lost due to some cheap cable that worked for other devices.

Upgraded to latest BenF firmware.
