The Winusb package is not available from this PPA for Wily but there is a technique that worked well on my system to install it using the Saucy package. I have tested this under Trusty but it should also work under Wily:
Firstly download either 64bit or 32bit package from the PPA:
64bit:
wget https://launchpad.net/~colingille/+archive/freshlight/+files/winusb_1.0.11+saucy1_amd64.deb
32bit:
wget https://launchpad.net/~colingille/+archive/freshlight/+files/winusb_1.0.11+saucy1_i386.deb
Then install the file:
sudo dpkg -i winusb_1.0.11+saucy1*
You will see errors such as the following:
andrew@corinth:~$ sudo dpkg -i winusb_1.0.11+saucy1*
(Reading database ... 197467 files and directories currently installed.)

dpkg: dependency problems prevent configuration of winusb:

winusb depends on gksu; however:

Fix the errors:
sudo apt-get -f install
It is a very clumsy method (and certainly will not work for all deb packages!) but has certainly worked on my Trusty system and should also work on Wily:
