Environment variable "USBPATH" doesn't seem to work

[LordMike]

$ docker run --rm -it --security-opt seccomp=unconfined --device /dev/aeotec_zwave -e USBPATH=/dev/aeotec_zwave openzwave/ozwdaemon:latest
USB Path "/dev/ttyUSB0" does not exist or is not a Character Device 
failed to resize tty, using default size

Seems USBPATH wasn't used.

It should be USB_PATH
