Um, bring up the device manager. Unplug the unit. Wait a minute or so. Device manager should self update it's display. Plug in the unit. If it is erased it should come up as a serial port after device manager thinks a little bit. Try rescanning for equipment changes. (Highlight one of the device classifications, any one. Then the Action menu will over "Scan for hardware changes".) If none of them shows a new device is found you're into needing Youssef or somebody to help. If a device comes up with a yellow question mark it suggests it is something the system does not recognize. That is also a job for Youssef and company. It should come up as a BOSSA serial port, in an ideal world after it has been erased.

DO NOTE: After erasure UNPLUG IT. Then plug it in. Then try to flash it. Some steps on the initial flashing process may seem silly. They are not.

Thanks for all the ideas: Here's what I've done. Cumulative and stopping with each step to try. So far no luck.
- Scraped the erase pads and re erased the unit, being careful to hold it for a full 1 second. Took all external devices off my laptop. Checked the computer that Port 10, 11, 12 wasn't in use. (In fact no ports were listed.) Same as previously.
- Changed cable. Same as previously.
- turned off virus protection, internet, and firewall. Same as previously.
I think those were the relevant suggestions I hadn't tried before.
Repeated this on 2 other computers with same responses - 1 laptop and 1 desktop. Originally on a MSI laptop, then a Lenovo laptop, then a HP desktop.
It's pretty clear that the flash software isn't finding the unit even with downloading the flash software to 3 machines.

Just a small note based on my personal experience. At first, shorting the
two "Erase" pads as shown in the photo did not work...
Then I realized that maybe the pads could have been covered by a transparent
layer of protective (and insulating...) paint.
I disconnected the unit from the USB port, and gently scraped the top of the
two pads so to expose the bare solder.
Then I reconnected the unit to the USB port, and repeat the shorting procedure.
This time everything worked as it should, and was able to correctly flash
