I am using:
$ uname -a
Linux debian 4.3.0-1-amd64 #1 SMP Debian 4.3.5-1 (2016-02-06) x86_64
GNU/Linux
$ apt-cache policy libusb-1.0-0

And I can't reproduce the problem :-(
I tried connecting a USB memory, my Android phone, a USB hub but it
all worked as expected.
That bug is even more strange now.
Maybe enabling libusb debug would help. I will try to document how to
do that easily.
Bye
