I have not tried that yet, but I was reading about the E220 on Wikipedia and this is what it says about it:
"The device comes with two cables, one short and one long. The long one has two USB A interfaces, one used for data and power and the other optionally only for assistance power in case the computer is not able to provide the full 500 mA (milliamperes) required for the device to work from one USB interface only. If the connection is frequently disrupted or is unstable (or usable at slow speeds only), the two plug USB cable should be used instead." Could it be possible that it's not getting full power which makes it unstable at times? This issue only happens sometimes. Mine only came with one cable. Not sure where to get the other kind of USB cable. On Fri, Jul 10, 2015 at 9:48 AM, Alvaro Cornejo <cornejo.alv...@gmail.com> wrote: > Hi > > Have you tried to deleted manually from a terminal ?
