[Solved] Wireless USB adapter not being recognized at startup.

After the system update of 29/08/2016, my wireless usb adapter Cisco AE1000:

Bus 002 Device 006: ID 13b1:002f Linksys AE1000 v1 802.11n [Ralink RT3572]

is not connecting automatically on the internet, the network-manager-applet on my Gnome panel is not showing any adapter, the solution I'm using is to unplug the usb adapter and replug it, after doing it everything goes the way it should be and I'm automatically connected to the internet.

Here is the log from /var/log/pacman.log in the day of the update.

Someone knows what is going on?

Re: [Solved] Wireless USB adapter not being recognized at startup.

I am confused. You say USB adapter in the title, and you state that you hot plug it; but the output you provide is that of a PCI device. (PCI-e, specifically) Original post updated

I don't use NetworkManager, but a recent upgrade of it caused some major issues.  Be sure to read the stickied topics on NM.

When it is not working, and again when it is working, post the output of ip link
Also, the output of lspci -nn and of lsusb

Sorry, I mistook the devices, I edited the first message with the correct device information.

Yes, I read a topic with some people downgrading the networkmanager package: https://bbs.archlinux.org/viewtopic.php?id=210868.

I tried to reproduce this problem again but unfortunately this behavior happens interchangeably and I can't get this information you ask right now, the next time I am able to reproduce this behaviour I will post here the logs before and after the device being recognized.
What I can post right now is the output of lspci -nn and of lsusb:

Re: [Solved] Wireless USB adapter not being recognized at startup.

I looked in the network-manager-applet and my previously saved home wifi connection had disappeared so I re-saved this information and it seems that I'm connecting successfully at startup. Meanwhile I'll let this topic marked as solved.
