It seems that the last version of CGMiner that could find all 5 of my USB Erupters immidiately on every start is 3.6.4
Any newer version of program finds randomly 0 to 5 devices. Sometimes it happens certain device is not found even
after few hours. What exactly is changed after version 3.6.4 that affects USB Erupter detection? Im using Win7 64-bit
but issue exists with WinXP 32-bit as well.
