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:

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