I got 48 asics working last night on one Windows 7 mining rig.  During the night 12 dropped off (on 2 hubs that were daisy chained).  It was impossible to know which ones were disabled so I had to reboot the whole system.

I used cgwatcher to start cgminer and it gives you device details as well as all of the normal metrics - accepted, rejected, etc...

I used the zadig_2.1.0 to change the driver to WinUSB.  Started cgminer and reset all of the hubs.

All of that was on a mining rig with 3x7970s as well.  I was getting 20 Mhps on that rig.

I tried putting 8 asics on my personal pc and can't get more than 7 up.  I am thinking my pc has a lot more software and driver changes than my mining rig which was designed only for AMD Catalyst software, cgminer and cgwatcher.


I cant wait for a version of cgminer that will see the devices on startup.

Good luck!
