WiFi Dongle doesn't work after update

[thofregato]

Hi,

I have a Raspberry Pi 2 Model B and (with raspbian) I have always used my USB WiFi Dongle (Linksys WUSB600N).
Now I upgraded to the last version of Raspbian and the Dongle doesn't work.
If I type lsusb it does not appear.

If something does not appear in lsusb, you should see messages in /var/log/syslog. They will mention some sort of problem. Find the messages. Look in syslog a few seconds after plugging the device in.

You can also google the device model to find the chipset. Unfortunately many manufacturers change the chipset without changing the model number.

I have this in my logs:

The dongles worked untile the last update to Raspbian+Pixel

Could be power problem.

Google device descriptor read/64, "error -32"

Most of the posts suggest a hardware change. Could be a change in the software causing a higher power draw somewhere or detecting an error that was not previously detected. To eliminate, or identify, the power draw problem, please test with the Wifi in a powered hub.
