To create a debian install stick, one copies the iso to the device:

cp debian-testing-amd64-DVD-1.iso /dev/sdb

per this page:

https://www.debian.org/releases/jessie/amd64/ch04s03.html.en

according to this SE question:

How to check progress of running cp?

one can monitor the progress using stat -c "%s" /dev/sdb

Despite the light flashing activity on the thmubdrive, stat is reporting 0

I tried rsync, but rsync fails, reports 'no space left on device'

dd would be a more appropriate tool for the job in this case and if you use pipe viewer you can pass the dd command through it. e.g

dd if=debian-testing-amd64-DVD-1.iso | pv | dd of=/dev/sdb

if you use the --size/-s option and specify an approx size it will also try give an approximate time.

dd if=debian-testing-amd64-DVD-1.iso | pv -s 3G | dd of=/dev/sdb

You simply can't since cp has no monitoring functionality.

The SE question you refer to relies on a filesystem which is not your case. How could any application know what represents actual data as opposed to random junk present on the drive?
