Title: Help with CGMiner! Post by: AJM on September 22, 2012, 07:56:10 AM I just installed another graphics card and now cgminer is saying "All devices disabled, cannot mine!".
For reference I am running windows 64bit. Any help will be greatly appreciated. Title: Re: Help with CGMiner! Post by: os2sam on September 22, 2012, 07:18:53 PM Did you try posting in the CGMiner thread? That's a good place to receive CGMiner help.

For reference I am running windows 64bit. Any help will be greatly appreciated. really not a cgminer issue.. windows issue. check in computer->manage->devices->display adapters windows is always the same/similar steps try each, if not working, try next reboot shut down, change cards around, make sure power is properly plugged into cards.. reinstall drivers uninstall gpus, reboot start removing cards one by one, or start with one and add one by one sometimes you have to install drivers twice (i do the full CCC install) Title: Re: Help with CGMiner!

First tried reinstalling drivers....same issue Tried uninstalling and then installing drivers.... same issue Finally just did a clean install of Windows and all drivers....WORKED!

A windows reinstall was compleatley unneccessary, My bet is that you never Properly uninstalled the drivers' SDK, by running something like Driver SweeperFirst tried reinstalling drivers....same issue Tried uninstalling and then installing drivers.... same issue Finally just did a clean install of Windows and all drivers....WORKED!

Post by: cygan on September 30, 2023, 12:01:11 PM i didn't want to open a new thread now and post my concern here, because i think that the topic title fits to all cgminer problems in general ;)
wanted to restart all my miners (5x compac f and 2x r909) today, since a long time. after i execute the ./cgminer ... command, i get the following message: Code: [2023-09-30 13:56:41.380] No devices detected! i have not changed anything at all on the system (rpi4) and version 4.12.1 of cgminer is installed - anyone got an idea? Title: Re: Help with CGMiner! Post by: DaveF on September 30, 2023, 12:29:28 PM An 11 year necro-bump. I think that is a record.
If you run lsusb https://linux.die.net/man/8/lsusb What devices are listed. And the obligatory, did you reboot the Pi and power cycle the USB hub(s) that the miners are plugged into? Also, if you plug in a basic device like a mouse into the hub(s) with the miners does the OS see it? -Dave Title: Re: Help with CGMiner!

I think that is a record. hehe, why should i create a new thread when i found this one already created via the search function ;) If you run lsusb https://linux.die.net/man/8/lsusb What devices are listed.

Also, if you plug in a basic device like a mouse into the hub(s) with the miners does the OS see it? -Dave of the 3 available usb ports, the usb mouse only does not respond on the usb 3.0 port (a hard disk is connected to the second blue (usb 3.0) port) Title: Re: Help with CGMiner! Post by: DaveF on September 30, 2023, 02:13:02 PM Although not 100% the same you should be seeing something like the below showing the attached devices.
If not something else is wrong. Check all the cables and connections and such. Since it's not responding to the mouse, I would point to something with the USB ports themselves. Can you plug the miners into a different device to see if they are seen there? If that works then it's probably the Pi if they do not work in the other device then it's probably it's the cables or USB hub. -Dave If the fan was pulling extra juice and also plugged into Port 1 or Port D it might have messed up the power going to the hub chip. Any other ports should be pretty much bulletproof. If you plug the hub in and run 'lsusb' it should read out a Terminus FE2.1 7-port USB hub on the bus. It does now which is weird. It didn't when the fan was in port 1. Code: pi@RPi4:~ $ lsusb Thanks to everyone for the help and getting me up and running with this small poject. Title: Re: Help with CGMiner! Post by: BitMaxz on October 01, 2023, 12:54:06 AM ~snip~ Does your USB hub have separate power? Check the power supply it might not giving enough power if you have an extra power supply you can test it or try to run your miner one by one. Also, make sure the USB hub is connected only to USB2, not USB3. If it still doesn't work you might need to reinstall everything on the RPi4 you can follow the guide on Kano.is or check the troubleshooting guide below - https://kano.is/gekko.php#trf Title: Re: Help with CGMiner! Post by: decryptit on October 02, 2023, 02:39:54 AM Hey guys. I'm glad I found the right thread. But basically, I've been trying to mine testnet btc using cgminer but no success so far. I'm getting multiple errors. One is Fatal JSON error. The other is need to specify at least one pool server.
I am basically trying to mine with my Windows computer using the built in GPU which is a AMD 550. The cgminer that I am using is 3.7.2. I've seen other version like 4.9.2 but it seems like that version is for asic only. Could someone post a sample cgminer config for me? Also, I have a testnet full node running. I am supposedly having a P2Pool running also via dockerfile. It shows online. But maybe my config is wrong or something. In any case, can someone post a sample of how I should config my cgminer for a single GPU on a Windows desktop? Thank you. Title: Re: Help with CGMiner! Post by: kano on October 03, 2023, 08:07:44 AM There is NO GPU mining in cgminer.
Title: Re: Help with CGMiner! Post by: kano on October 03, 2023, 08:10:20 AM Code: pi@raspberrypi:~/cgminer $ lsusb Since it shows no miners, it's one of: Your hub is dead You forgot to put power into your hub Your hub power is dead Your miners are dead You forgot to connect the hub cable to your rpi The hub cable is dead Your rpi is faulty Title: Re: Help with CGMiner! Post by: cygan on October 03, 2023, 10:57:57 AM lol i found out what the problem was...
no miner was broken, no cable was broken and no other hardware was broken... i was not logged in as administrator - after i activated the su, all my 8 miners started without problems ;D how could i have missed that... :-X :P ::) Title: Re: Help with CGMiner!
