Just a little FYI for R Pi B users:
They screwed up the circuit board layout on the R Pi B by refusing to follow the trace layout requirements set out by the USB chip manufacturer. They didnt use correct values of bypass caps and made tuned traces of the wrong layout.
I reverse engineered their "wont work with long USB cable or hub" failures and found the gremlin...
Theres no excuse for producing a device claiming USB operability that wont work to the USB standard. I guess third World buyers wont notice? (sarcasm) They HAD to know about the failure right up front.
These con artists have screwed thousands of people with this junk. especially the US Distributors I NOTIFIED who kept selling them. Yeah, MCM and Newark, thats you.
