gridseed detect (4:4) failed to initialise (incorrect device?)

[l0c0luke]

(Thanks for the OSX fix!)

When I startup cgminer, I get the message above. I am trying to start it with

./cgminer -o stratum+tcp://doge.us.1coinpool.com:3334 -u xxxxx -p xxxxx --scrypt

Does it work if you run it as root? You might need to adjust USB permissions, but I have no idea how to do that on OS X.

I had tried running as root. I didn't attempt to alter the mode of the devices though. Ultimately I got this damn gridseed working with the cpuminer included with the macminer app so I guess I am content. You can close this issue if you want. I presume it was a setup problem on my end. THanks for looking at it though.

I've running into the same issue (running as root) when running more then 9 gridseeds

cgminer --retries=3 --api-listen --api-allow=192.168.1.66 --gridseed-options=baud=115200,freq=850,chips=5,modules=1,usefifo=0,btc=0 --hotplug=30 -u xxxx -p xxxx

I'm seeing the following error messages

I've disabled hotplugging and I'm no longer seeing the gridseed detect (1:78) failed to initialise (incorrect device?) issue. I haven't seen any timeouts since then either. I'm still getting this error GetResults usb read err:(-99) LIBUSB_ERROR_OTHER which causes cgminer to restart.

Hi. I know it has been a while, but I was experiencing the exact same issue as @jeteokeeffe and for me the solution was simply buying a new PSU for the miner. The original PSU that came with it was making a cricket-like noise and the same day this started these error messages appeared. Probably it was due some kind of sudden power shortage or the voltage not being stable. I don't know because I am no electrician. In any case, hopefully this can help somebody.
