Re: [GUIDE] GridSeed Miner Support/Tuning

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.

I got it working with STM. Only downside was that when I was playing around with frequency, I had to disconnect and reconnect the units for CGminer to see them again.

What steps did you perform to get this working?

Thanks.

Exactly as written in the post you linked.
- Downloaded Zadig
- From the Zadig interface select Options and choose List All Devices
- From the Dropdown list of devices select STM Device USB and click on Replace Driver with the WinUSB driver selected
- Edited the .bat file in CGminer and ran it.

As mentioned, after stopping CGminer I had to reconnect the USB cable to get CGminer to see the devices again.

This isn't working for me, and the guys that hacked cgminer admitted they tested with earlier GS5's that had the CP2012 controller and not the STM controller. Not sure why you're having luck with this, I wish I was, maybe it's Win 8 vs Win 7? Regardless, word is that STM is not functional as there are a lot of people not able to get this to work.
