Any particular reason you need to define these instead of just using the
standard flags from linux/usb/ch9.h directly in the requests?:
(USB_TYPE_VENDOR | USB_RECIP_INTERFACE | USB_DIR_OUT)
(USB_TYPE_VENDOR | USB_RECIP_INTERFACE | USB_DIR_IN)
(USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_DIR_OUT)
(USB_TYPE_VENDOR | USB_RECIP_DEVICE | USB_DIR_IN)
If nothing else, using those from the beginning would have avoided the
mis-labelling you are fixing up.
