I see 1.0% - 1.5% errors on my erupters with a rosewill 330 USB hub and cgminer 3.3.1. I used zadig to install the usb driver on win7.
It's closer to 1.5% with 4-5 erupters, and closer to 1.0% with 1-2 erupters. My guess is that it's your USB hub or maybe the older cgminer version.
Topic: Erputers getting 7.7% HW error rate on Raspberry Pi and cgminer (Read 1749 times)
The hub provides 3A power (500mA to each) and I'm running 2 Erupters on it with no other devices.
I plugged one of the Erupters directly into my PC and ran it for around 12 hours but I still keep getting the HW errors, around 8%:

Code:

How much power can your ps provide?
plug one unit direct into your PC and post your cgminer output after some time

Update: I stopped running on the pi and moved to a PC running Xubuntu. After 18 hours the HW error rate was the same as on the pi, so the pi is not what's causing the errors.
At this point I suspect it's due to poor quality control on hastily-made Erupters, or my input settings are incorrect. I hope it's the latter because that can be fixed. Any suggestions?
I moved everything back to the pi...it's saving me at least 100 watts over the PC

I have 2 Erupters in a "Pluggable" powered hub on the 512 version of RPi running cgminer 3.1.1 on Raspberian. I have a fan pointed at the setup and no parts get over 55c temperature. It's been running for a little over 24 hours and I'm getting lots of HW errors (7.7%) with the following message:
