Without dettaching the device after failure, trying to reconnect to any of the dead serial ports makes console sput:

uticom0: uticom_param: STALLED
uticom0: uticom_dtr: STALLED
uticom0: uticom_rts: STALLED
uticom0: uticom_close: STALLED

Similar problems founds on a uticom usb to 4-port serial adapter.

Everything works for several hours, then stops working. This time
workload seems to be less involved; just at idle -some keepalive style
packets- the soft stops working.

No error messages at the console, and dettacching/reattaching the device
doesn't work.

Plugging device on another usb port brings it new life and, only then,
dettaching and reattaching in the original usb port makes it work again
without rebooting.

I wonder in what kind of mess I'm digging... Oh, my; I _knew_ USB is
_not_ serious xDDD

Here we go again with more info. The facts:

-uftdi USB to 4 port serial.
-Adaptor attaches fine, works for a while.
-After an amount of time, when serial load increases, the driver may
fail.
-After the failure error is unrecoverable; detaching/reattaching device
doesn't work. Must reboot the computer to get working again.
-After failure usbdevs seems different! -No messages in console indicate
any device change whatsoever-.

Driver seems to work just fine under light load, and has a stealth fail
-no errors on message log-:

Then you dettach device, console shows:

8<-----------------------

Trying to reattach is to no avail; doesn't show anything on screen.

Some advice???
