Hi.

Had a problem for a while with this 40M machine.
Seemed to be the USB, well that is how it looked as sometimes simply plugging in and out sorted it.
I was using various cables in various set ups.

Now it will not send nor receive - though it still gets hot and the fans spin.

I even replaced USB board inside with same one from my Zeus 10M rig.

CGMiner 3.1.1
EVGA 1300
F2Pool - LTC

Any help is appreciated

Thank you

or try

Cgminer v4.3.5-scrypt.2
https://github.com/dmaxl/cgminer/releases

are you using windows or Linux

whats your command line .

make sure the divers are still loading in device manager if it's a windows box .
for Linux use

sudo ldconfig
lsusb

bfg Drivers are here for windows

CGMINER driver are here for windows

Make sure the PSU is plugged in good, no wires are melting some place those miner tend to do that.

Sorry.

Windows 10

cgminer 3.1.1

cgminer.exe -o stratum+tcp://stratum.f2pool.com:8888 -u xxxxxxxxx -p xxxxxxx -S //./COM5 --chips-count 256 --ltc-clk 234 --ltc-debug --nocheck-golden

exactly same for the smaller rig except for the  chip count and clock numbers - that works fine

drivers should be ok as the other rig works.

Never used BFG couldnt get either to work on that :(

thanks

Cgminer v4.3.5-scrypt.2

^^^^^^
try that instead it came out last year other wise no idea

why wouldn't BFG work ? . just wondering most of the issues is using the wrong drivers.

These are for BFG and windows
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx

BFG uses different drivers then CGMINER did or does use .

uninstall the CGMINER drivers First if you try bfg again in the device manager then install the drivers BFG uses .

Other wise can't say, did you consider buying a A4 http://www.innosilicon.com/ which I'm guessing might cost to much or this is a hobby :) .

The A4's are real and innosilicon is the only company right now that makes Script miners.

I know it says a 100 buy but you can get in a group buy on the forums which in most cases is only the cost of the miner/s free shipping some times and discount because it is group buy .


PS keep looking for A2 110 deals now that the A4 that replaced the A2 110 is starting to sell  the A2's are dropping in price now you can buy a A4 136 MH for what some are still tiring to sell A2 110 for so be care full some folks are evil .

downloaded the cgminer you pointed to

edited the "example" bat file with my info --

ended up with  cgminer.exe --scrypt -o stratum+tcp://stratum.f2pool.com:8888 -u xxxxxx -p xxxxxx --scan-serial \\.\COM3 --zeus-chips 256 --zeus-clock 234
pause

getting :-

zeus detect: test failed at \\.\COM3: got 00000000, should be 00038d26

repeating except for new block report and work restarts.

will have a go with BFG later I think :(

thanks

added nocheck golden to command line

cgminer.exe --scrypt -o stratum+tcp://stratum.f2pool.com:8888 -u  -p  --scan-serial \\.\COM3 --zeus-chips 256 --zeus-clock 234 --zeus-nocheck-golden
pause

restarted and now get this --- but still no accepted shares

I am having problems with my Zeusminer x2 scrypt ASIC miner 28 mhz.  Same thing it seems, sometimes just plugging it in and out worked, or had to reinstall UART to USB, then Zadig. But now trying on two computers it's not accepting.  I don't mind becoming a WinUSB guru, but it seems the learning curve is slow because it's just a slog of information and not many people able to give tech advice to connect the dots.  Should I be editing registry now that it's failed?

Why the random workings and not-working? What is kicking it out?  Nothing in computers needs to be seen as random. Something is effecting the state of the machine.

I have tried to get it to work on the 2nd computer but not for very long.  I just saw it wasn't registering in Zadig after I installed UART to USB.  Zadig shows nothing but a webcam driver (which I never used and it has a built in one) and thought maybe it's the miner that's broken.

(((((( . ((  I have been playing with some Gridseed blades I just got hold of --- pain in the ass  lol  )) <--- \\.EDIT Got this sorted ))))))



Anyway back on topic.

After much more searching, I found a likely solution.
Seems the little info out there points to a failing PSU.
It may run the machine but not the juice needed to make the chips do what they should. ?

Got my hands on a 1850W PSU I need to wire up / solder etc.

Will report back if this is indeed the cause.

For some reason, there isn't a lot of Scrypt ASIC support here.  I think at least some of the small miners like Gridseed Orbs should be supported to help get the currency more accepted.  It's easy enough to hook one up, but when you start using several with the same computer and so on it gets more complicated.

It's very time consuming for newbies to figure some things out for themselves.  I'll keep my eye on these questions to see if I can help so I can give back, but I've only been doing this about four months.

NO support because no script miner are made like they used to be and script is only done buy a few miners X11 miners and script miners made to mine Script coins, if they made Script miners like bitmian makes BTC miners you would see more up to date support but there is tons of Script miner support if you look  though pages of posts here that hasn't been updated for years by years i mean 2 or more. so you won't see it unless you looks at the many pages on the forums but it is there :) .

Thanks.  I wonder if owners of the site would mind if it was all put in a PDF file somewhere.  Not sure if there is a files section anywhere.

you can ask to have it added but may not because of what others would upload to get access of accounts they other wise can't, if there in no section like that now . i haven't found 0ne. i guess that might be why there isn't and that would be a lot of work setting up the right monitoring software for that kind of uploads plus the site is here because of big donations from others..so it's all done free. you can do some thing like what you want to but might have to host it of site with a link .

My previous post was in relation to Zeus  not Gridseed :)

here is two links for Zeus miners that might help some : i owned like 6 of them at one time very small farm, I learned a lot from owning those few, mining is a fun and very addicting hobby for me and I just recently rebuilt a thunder x6  for fun.

I guess when they die they don't register as anything live when you plug them in a computer.  Is that the only way to tell if one is dead?
My fans go and the blue light is on inside but nothing else seems to register.

Right then.

New PSU

Hey presto --- machine works again.

SO  anyone who thinks their machine has died please get a replacement PSU :)


thanks for all input into thread
