USB: vstusb.c: removal of driver for Vernier Software & Technology, Inc., devices and spectrometers
This patch removes the vstusb driver and support from the Linux tree. This driver provided support for Vernier Software & Technology devices and spectrometers (Ocean Optics). This driver is being replaced by a user space - libusb - implementation. Signed-off-by: Jim Collar <jim.collar@eqware.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

- This driver is intended for Vernier Software Technologies
- bulk usb devices such as their Ocean-Optics spectrometers or
- Labquest.
- It is a bulk channel driver with configurable read and write
- timeouts.
-
- To compile this driver as a module, choose M here: the
- module will be called vstusb.
