I'm using CGMiner 3.1.1. I've got a Satechi UH-12P 12 port usb 2 hub, with an upgraded 5 volt, 6 amp power supply. When I run CGMiner, everything works fine for a few minutes, then 3 of the erupters will randomly start giving errors:

ICA1: invalid nonce - HW error
ICA0: invalid nonce - HW error
ICA3: invalid nonce - HW error

Not in that order though. It's pure random.

Here's my setting:

cgminer-nogpu.exe --icarus-options 115200:1:1 --icarus-timing 3.0=100 -S COM3 -S COM4 -S COM5 -S COM6 -S COM7

All help is appriciated!

Thanks.

BTC .5 BTC to whoever can help me get it fixed first, providing it can be fixed without buying new usb hubs! BTC
