*Hi, Guys!* I am trying to use my USB Token on Debian Jessie, but it turns on the light, and in three seconds, it turns off. So, the USB Token stops working.
I found in the Internet that it can be a power problem. They recommended to run the following command: *echo 'on' | tee /sys/bus/usb/devices/usb2/power/level* It changes the value on that file, but the behavior remains the same. In this way, I ask for help. My Debian informations are below. *uname -na* Linux ncc1701 3.16.0-4-amd64 #1 SMP Debian 3.16.39-1 (2016-12-30) x86_64 GNU/Linux *lsusb* Bus 001 Device 002: ID 8087:8001 Intel Corp.
