That is weird, they are indeed declared in libhid.h:

85 	extern HIDDesc_t        *pDesc; /* parsed Report Descriptor */
95 	extern reportbuf_t      *reportbuf;     /* buffer for most recent
reports */

But the definition is in usbhid-ups.c, so that should be resolved at link
time:

98 	/* global variables */
99 	HIDDesc_t       *pDesc = NULL;          /* parsed Report Descriptor */
100 	reportbuf_t     *reportbuf = NULL;      /* buffer for most recent
reports */

Why your linker (assume that is complaining) fails to see these, is beyond
me.
