USB connection trouble

Recommended Posts

Hello

I would like to share a trouble that I got with my UMO+.

From few weeks, I can't connect the UMO+ on my computer through the USB cable (SD card works perfectly). I get "Unknown USB device (Device Descriptor Request Failed)" on Device Manager under USB controllers.

This problem appears few days after to install a USB 3.0 hub on my computer and connect the printer through this hub. But now the problem appears on all USB ports

My computer runs with Win 8.1

UMO+ works with CURA 15.04

Also I use Arduino 1.6.8 software for an Arduino UNO card

I already try to:

- Reinstall CURA and Arduino (old and new version)

- Try to connect UMO+ with MatterControl 1.5

- Desinstall Device in the Device Manager and restart computer to reinstall the device

- Try to install drivers manually

- Install CURA on an another computer which use Win XP

- Change USB Cable

Unfortunately nothing works

Have you any suggestion to solve this problem ?

Thank you very much

Sébastien
