man ugensa doesn't exist! As I wrote earlier, I tried everything to load what I could
find. It seems, the patch and the hint about ugensa.ko did the magic ;-) Thank you very
much! Could the patch be made permanent to FreeBSD CURRENT?

And also important: where is the man page for ugensa? Can the the module be compiled
staitcally into the kernel or are there pitfalls?

root_at_localhost: [src] kldload ugensa

ugen2.7: <Digi International> at usbus2
ugensa0: <Digi International WatchportT, rev 1.10/1.00, addr 7> on usbus2
ugensa0: Found 1 interfaces.
root_at_thor: [src] man ugensa
No manual entry for ugensa
root_at_localhost: [src] ll /dev/cuaU0*
203 crw-rw----  1 uucp  dialer  -  0xcb Jul 24 07:51 /dev/cuaU0
204 crw-rw----  1 uucp  dialer  -  0xcc Jul 24 07:51 /dev/cuaU0.init
205 crw-rw----  1 uucp  dialer  -  0xcd Jul 24 07:51 /dev/cuaU0.lock


I'll try now to get informations out of the device, I let you know whether that is a
success. But anyway, again, thank you for helping making the device visible and available.

Kind regards,
