Since this is still a happening thread, I'll provide an update:
As I said all along, this was caused mostly by driver/connection issues and there is not a standalone CPU updater available for this scanner as there is for the Whistler branded ones. Well, there is, but I guess it enables the scanner to do too much, so some folks get upset. Being upset that people can't get their scanners working and try available tools is certainly something to be proud of.
Anyways, someone was nice enough to send the original RS Pro 668 software, which finally worked on the third computer tried.
Just a case of the typical connection problems seen with this line, only the tool to fix it in this case is unavailable due to what appears to be petty business decisions that punish customers who would otherwise be loyal to a product line instead of the intended entity, which could not care less. Yay for treating people right!
Nyscan, why would they treat you nicely and give you a deal? This is EZ Scam. Fork over the cash $$$. Gotta get back at the big bad shack by sticking it to you. They ought to be doing mail in firmware upgrades for free, to be honest. Shipping products with connection issues is not good.
