I ordered two gridseeds from GAW on Monday and received them both on Friday.  They came with both USB and power pigtail connectors.  Setup was easy.  I spliced the pigtails into my a spare PSU cable on my desktop, installed the zadig_2.1.0 and changed the drivers of both stm32 virtual com ports to WinUSB and was good to go with cgminer for gridseed http://cryptomining-blog.com/wp-content/files/cgminer-3-7-2-gridseed-windows-oc.zip.  Both units run at 377.9khash and have been stable without hardware errors for 21 hours.

Thanks guys!
