Topic: [GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning - page 47. (Read 308807 times)

I had the "One of the USB devices attached to your computer has malfunctioned, and Windows does not recognize it." with one pod and nothing I did helped.  I tried it on 4 computers with fresh driver installations.  At the time, I didn't know about a reset button on the pod.  Maybe try that if you are comfortable taking the heat sink off.  My pod was still under warranty so I returned it. 

Don't use Zadig for your testing.  Use CP drivers for pods with CP com chips.  Use STM drivers for STM com chips.  Reinstall the correct drivers and see if Windows recognizes the device.

thank you for fast answer. I have not found anything about this chips. so i have buy a 1RA03GMT mosfet for test. i have implement it and it works. my soldering looks not good but my gridseed hashing since 24h.

I followed the steps, install CP210x_VCP_Windows, plug in device, run zadig_2.1.0.exe, but then I get this:

Tried uninstalling and reinstalling, tried reinstalling Windows, tried different ports, hubs, etc.
LED is solid green sometimes, other times just the FAN is on.

Yes, there is currently a display for chip/miner/total hashrate.

Wow do it please, Really would love the CPUminer with auto overclock for windows.

any chance to make a fix to show hashrate as well? I'll donate for that!

I have not yet pushed the auto overclock feature to github as it is still undergoing testing, but look forward to it this weekend.

I will test cpuminer again.
Anyone tried using this version of cpuminer?: https://github.com/siklon/usb-miner/tree/master/software/cpuminer
It has auto frequency tuning per chip as used in LightningAsic Gridseed Controller Firmware V3.

Same for me CPUminer has been the best for me, no reboots needed, no errors, perfectly stable. I Tried BFG, was a mess..

I haven't used those. I use cpuminer. Seems stable for the past several days. On Win XP too.

I have compared Bfgminer with Cgminer using gridseeds. It's interesting how both behave with p2pool:

Bfgminer seems to have a higher total hashrate, but the rejectrate is about 8%. This is normal for p2pool.
Cgminer's total hashrate is a bit lower, but the rejectrate is extreme low, about 1%. That's very nice.

Unfortunately, cgminer crashes every now and then while bfgminer is rocksolid.

Hi Guys,

I am not sure what I am doing wrong, I have downloaded cgminer OC version

and followed the steps for cgminer, which worked with 1 Gridseed
Installed Zadig plugged in 1 gridseed to test and and then replaced the driver to WinUSB (v6.1.7600.16385)

Ran the BATCH file

cgminer.exe --scrypt -o stratum+tcp: ETC ETC ETC ETC --failover-only BLAH BLAH yougetthepoint --gridseed-options=baud=115200,freq=888,chips=5 --hotplug 0

pause

and it started to work which made me happy although:

1st problem: I started to play with the frequency by changing the batch file saving then closing and re-opening cgminer, for some weird reason when I close and re-run the batch file it doesn't detect the gridseed, its like I have to unplug the USB connector and re-plug it back on and THEN restart cgminer and it will then pick up the Gridseed.

2nd Problem: I started to plug in more devices , for eg: I plugged in another 1 and then I realized it automatically went to WinUSB (v6.1.7600.16385) by itself no need to re-do it again, while I was doing this cgminer was still running with the 1st gridseed all of a sudden I got an error libUSB error and its like cgminer lost connection with the gridseed. Now when I run cgminer it doesnt pick up any gridseeds, I checked Device manager and all 3 are under USB - showing as >> STM32 virtual com port which seems correct after what I read.. I looked in Zadig and all 3 are there with the same version WinUSB but something I thought may not be right , I looked at the USB ID in Zadig and all 3 have the same ID 0483 5740

Please help guys I don't know what I am doing wrong

does the batch file need to change or something, I did not see this is any of the guides It just said run the same batch that I posted above

PS: I even sometimes get a CGMINER is going to close error when I have been trying things and re-running the batch file, then the 2nd time I run it it wont close but still doesn't find any gridseeds


EDIT: Seems I found a bandaid solution , So I changed the Hotplug to 5 and then opened cgminer, and started plugging them in one by one. Seriously is this the only way with CGMINER, i am very surprised no one has fixed or modified cgminer to solve this. I am curious why the instructions say Hotplug 0 and why isnt this fix in any guide, I happen to accidentally stumble across a thread where someone was having the same issue as me

LTC is fine. PM me your offer.

How much you looking for? pay in LTC?

Anybody interested in buying raspberry pi + SD card loaded with hashra image? Have 3 available.

You are right...but Phobia is cheap...$5.99 for 0.5mm thickness...120mm x 20mm x0.5mm...

If you need thicker...1.5mm is $7.49 ...will cover about 5 Gridseeds ... 5 chips each ...TOP ONLY ...bottom is flat enough IMHO ...Th. Paste will do...

Copper shims are useful for really BAD GAPS...like 1 in 10 miners ...$0.15 a piece...

Whatever works for you, buddy...

ZiG

absolutely agree! i'll definitely pass here.. when it comes into buying these shims and pastes. cheapo pads, but a little bit thicker will do.. these poor shitcans are not worth such investments anyway. imo.

Hey guys,...

If you take the time to read my original posts...you will find that I am using also copper (XBox or RAM style) shims...cheap @ Amazon or E-bay...they are filling the gaps ...and thermals too...no Dremel...

Your mileage may vary...Decide for yourself...

ZiG

1mm pad may be not enough. at least for some of these shitcans.. 1,5mm...2.0mm needed

I have used the Phobya pads in the past on GPU's and they worked well. In order to do all the 20 of my units I am going to need a fair amount of pads. How many units can you cover with one of the Fujipoly sheets?

They will...but nobody knows how good are they...

I am using this...

If you follow my posting...a few postings up...the guy after my post in Gridseed support...is recommending even a better one...:
