Re: CGMINER GPU FPGA overclock monitor fanspeed GCN RPC linux/windows 2.4.4

Win 7 x64
9x BFL Singles
10 Port powered USB hub

Issue: Neither 2.4.4 nor 2.3.6 will start more than 6 BFL singles

Troubleshooting:
- Multiple restarts usually resulting in BFL singles receiving different COM numbers than previous reboot
- Powering and unpowering USB hub
- Plugging USB hub into multiple USB 2 ports will cause zero BFL singles to start in cgminer
- Plugging into USB 3 port will allow 6 BFL singles to start in cgminer, but I receive a, "This device can perfom faster when plugged into a USB 2.0 port," message
- Plugging the 3 BFL singles that where not starting in cgminer into another computer directly to the front USB ports. None would start resulting in same COM errors (2.4.3)

At this point I'm trying to figure out if the USB hub, cables from hub --> singles, cgminer, or the singles themselves are the point of error. All singles light up and the fans spin. Any help would be greatly appreciated.

I'm pretty sure I've seen this before. If you resize the window cgminer runs in, it might fix it.

Window size is already set to 87x56. I've tried increasing it upto 90x80, but it has no effect.

Pictures:

I just went and purchased a 4 port powered USB hub to test out if my 10 port was an issue along with some hardware to reassemble my 10th single. Out of the four singles attached to the new hub zero will start in cgminer. Using multiple rear USB 2/3 ports for the hub has no change. This almost added to the issues as now one of the BFL singles is not being assigned a COM number (Com 38, 39 ,Blank, 41). It should be 40, but that will not work either. With the four port hub added to the system I can now only get 5 singles to start in cgminer. This is pretty much driving me insane.
