I bought a Wi-Fi adapter to use on my Pi 2. I've already installed the driver rtl8192eu, (found on github). but, when I run lsusb, the Pi cant recognize the Wi-Fi adapter, it just shows me:

Bus 001 Device 005: ID 2357:0109

when I run lsmod, I get this:

when I run iwconfig, I get this:

lo        no wireless extensions.

eth0      no wireless extensions.

I'm using kernel version 4.4.50-v7+ and I would prefer not to upgrade it for a newer version.

can anyone explain what is happening and how to solve this?

when i do lsusb, rpi cant recognize the wifi adapter

Bus 001 Device 005: ID 2357:0109

That output is fine. That's how the device identifies itself. I believe the string often shown (e.g., Acme 0.1 wifi adapter) is one the kernel gets from somewhere, but not necessarily an actual driver because it will identify devices with no driver too. Perhaps it comes from the device -- in any case it is not important.

when i do iwconfig, i get this

wlan0 unassociated Nickname:"<WIFI@REALTEK>"

If the driver works well enough for that, most likely it will work in general. If the driver did not work, the interface would not be listed at all.

None of this amounts to a problem.
