description:
Add uxrcom driver for Exar XR21V141x USB serial adapters. Based in part
on the OpenBSD single-port XR21V1410 uxrcom driver, but adds support
for multi-port chipsets and uses the common umodem framework instead of
being a standalone driver.
Thanks to skrll@ for much USB clue and mrg@ for financing the
development of this driver.

+.Sh HARDWARE
+The
+.Nm
+driver supports serial adapters based on the
+XR21V1410, XR21V1412 and XR21V1414 chipsets.
+Devices range from single port to eight port (implemented as a
+USB hub and two
+.Nm

+.Sh DESCRIPTION
+The
+.Nm
+driver attaches the Exar XR21V141x multiport chipset with individual
+port drivers via
+.Xr ucom 4 ,
