Hi,
what could be the matter if block erupters getting slower after a few days?
I still see hashrate after 5s ~335 Mh/s but on the average side i only have ~220 Mh/s.
Im using D-Link DUB-H7 hubs on desktop machine with Ubuntu 12.04 x64 and latest, self compiled, cgminer (3.4.3).
Any hints would be nice
