Topic: High CPU usage in Windows 7 With CGminer and 58 Block erupters (Read 1333 times)
Thanks for the info. Can the hotplug setting be changed while mining?

Well, not really. I know someone using 38 erupters on cgminer on an RPi that uses 3% CPU. Admittedly that's a linux whereas you're on a windows. Some windows USB drivers consume a lot when they're used for the hotplug aspect in cgminer (specifically I think Nvidia's chipsets were the worst). If all your erupters come up straight away you can disable hotplug entirely with --hotplug 0, or probably better to just set it to less frequently in case a device drops out and needs to be hotplugged, to say every minute with --hotplug 60

Title says it all. Have intermittent 40-60% cpu usage while mining using CGminer 3.8.1. Using the Winusb driver and 58 block erupters.
Also the erupters occasionally seem to be "stalling" or waiting for work (green led lights up for about 2-3 seconds). I isolated the cpu usage to the plug
and play service. Maybe this is just USB overhead? Kinda makes sense with 58 erupters.
Computer is a Core 2 duo 3Ghz with 4Gb ram. Machine
acts as a file server and mines, nothing else.
