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.

Wow! what a convoluted mess cgminer is...at least with GS5's... my gosh!
All that configuring and re-configuring, tech support issues like crazy!
It seems cgminer has a way to go yet to become 'user friendly' i.e. easy and convenient for most users.
I'm using cpuminer LTC only version, and running smoothly, no comm port issues, no Zadikitup to hassle with.
Just dump zadic and cgminer for GS3355 and use cpuminer for Gridseed 5-Chip ASICs with Reduced Power Usage.... http://cryptomining-blog.com/1165-download-cpuminer-for-gridseed-5-chip-gc3355-asics-with-reduced-power-usage/
Forget about all the headaches and LOST TIME AND INCOME courtesy of cgminer for GS3355...
Load up and run cpuminer, get them running and making you MONEY stably and dependably!
Headaches, hassles and wasted time gone!
I for one am not interested in being some well meaning hacker's guinea pig....
Good luck!
