EPICS support for Ocean Optics QEPro spectrometer
This driver uses the Ocean Optics seabreeze open-source library.
USB permissions must be modified. Create /etc/udev/rules.d/50-usb.rules, with the following line in it:
SUBSYSTEMS=="usb", ATTRS{idVendor}=="2457",ATTRS{idProduct}=="4004",GROUP="root",MODE="0666"
This will mount the QEPro with read/write permission for owner, group, and other users.
