Thanks for reply Réna,

I did not download version of Zadig ( USB driver )
That appeared to be for Windows machines.

Seems I have left out an important detail, my operating system. Sorry.
running Ubuntu 16.04
( Also tried it on Linux Mint 17 , similar results. j
I do not have easy access to Windows , but probably can find one if I have to.

I got a TinySaber at the Detroit Maker Faire last weekend.
(my wife also got a Tiny Piano )

using arduino IDE 1.8.5
board: "TineSaber Rev2"
programmer: "arduino as ISP"

trying to upload the sample TinySaber code.
the sample code does verify.

this is the output from upload attempt.

Code Select Expand

Running Digispark Uploader...
Plug in device now... (will timeout in 60 seconds)
Warning: device with unknown new version of Micronucleus detected.
This tool doesn't know how to upload to this new device. Updates may be available.
Device reports version as: 2.3

What am I doing wrong here. 
Thanks for any help.

Roger.
