Guys
I'm really sorry but I'm going to withdraw this driver.
The actual piece of kit that I have is a DSB28-ZWEU .
The original driver I released I managed to get working on this hardware.
I have since received a ZW095-C which does NOT work correctly with this driver.
I don't want to disappoint but until I can get this sorted I'll remove the driver from GitHub.
It may take a while!
Andy
