usbreset: remove redundant package
The package `usbutils` already offers an USB reset function, this package is therefore not really required standalone. CC: Jo-Philipp Wich <jo@mein.io> Signed-off-by: Paul Spooren <mail@aparcar.org>

-There is a way to suspend a USB device. In order to use it,
-you must have a kernel with CONFIG_PM_SYSFS_DEPRECATED turned on. To
-suspend a device, do (as root):
-
- echo -n 2 >/sys/bus/usb/devices/.../power/state
-
-where the "..." is the ID for your device. To unsuspend, do the same
-thing but with a "0" instead of the "2" above.
-
-Note that this mechanism is slated to be removed from the kernel within
-the next year. Hopefully some other mechanism will take its place.
-
-> To reset a
-> device?
-
-Here's a program to do it. You invoke it as either
-
- usbreset /proc/bus/usb/BBB/DDD
-or
- usbreset /dev/usbB.D
-
-depending on how your system is set up, where BBB and DDD are the bus and
-device address numbers.
