So from the looks of the comments here http://cryptomining-blog.com/1262-download-cgminer-3-7-2-for-windows-scrypt-mining-on-gridseed-5-chip-gc3355-asics/#comments the STM etc.. isn't supported yet?

Also I tried this in linux and all the devices are shown and hashing but getting 100% reject and no shares are being offered.

run with --gridseed-options=baud=xxxxxx,freq=xxx,chips=x and --scrypt and it should work.

In linux I tried that but go none accepted...

regards,

P.
