I have Ubuntu Mate 15.10 on a USB flash drive. I booted into it and looked to connect to my wifi and it was not listed in my networking connections. I looked in network connections in the system menu and it doesn't have any wireless adapters listed. Only the ethernet.
I've run lsusb and my wireless adapter is listed there. I just don't know where to go from here in getting it running. Learning this as I go.
Thanks for any help.
EDIT 1 - Here is the output from lsusb:
