If I do not want to touch th USB stuff, can I get the same effect by close/open

The uslcom driver only does this right after attach, in 13-stable and 14-main.
Does the attached patch make any difference for you?

As this is a production server, I try to avoid reboots.
Meanwhile, I have inserted a read loop which eats the fragments
and allows the following status query to get a clean response.
With this patch, recovery seems to work.
Additionally I have eliminated a hub and connected the device directly to a
port.
Hopefully this will stop the frequent `/dev/cuaU0: Bus connection lost`events.
Thanks for your time,
Axel

You just need to rebuild the uslcom.ko and kldunload it.
make -C /usr/src/sys/modules/usb/uslcom all install KMODDIR=/boot/kernel
