Hello Forum

the devices worked for a few day using cgminer (first on windows then linux)

after the last linux reboot i got the appended errors.
Device is nether working on linux nor on windows.
Got Any ideas? Firmware update?

I checked the cables... everything fine.
Seems like the USB Controllers of the mining devices are bad.

Best regards bcm42

Try running it on a different computer? Its possible the USB port on your computer went bad, instead of the USB cable on the miner
