+===============
+
+NAME
+----
+richcomm_usb - Driver UPS equipment using Richcomm dry-contact to USB
+solution
+
+NOTE
+----
+This man page only documents the specific features of the richcomm_usb 
+driver.  For information about the core driver, see linkman:nutupsdrv[8].
+
+SUPPORTED HARDWARE
+------------------
+The Richcomm dry-contact to USB solution is a generic interface that is
+used to upgrade an existing (RS-232) contact closure UPS interface to USB.
+As such, all the limitations of the underlying contact closure interface
+apply.  This means that you will only get the essentials in ups.status: OL,
+OB, and LB.  See also linkman:genericups[8].
+
+BUGS
+----
+Most contact-closure UPSes will not power down the load if the line power 
+is present.  This can create a race when using slave linkman:upsmon[8] 
+systems.  See the linkman:upsmon[8] man page for more information.
+
+The solution to both of these problems is to upgrade to a smart protocol 
+UPS of some kind that allows detection and proper load cycling on command.
