I've never had as many problems with a new distribution as
with 15.0 I hope there was a good reason to have so many
configuration changes. ssh doesn't work the same as it did.
Console display defaults to UTF-8, yada yada...

I don't seem to be able to get a USB storage device
recognized. After building gpsbabel I get:
Failed to claim interface 0: Device or resource busy
error. Searching for a solution this is supposed to work:

echo -n "1-1:1.0" > /sys/bus/usb/drivers/usb-storage/unbind

but this results in:

-bash: echo: write error: No such device

I'm not even sure what the echo is supposed to do, but
it doesn't fix the problem. Same problem for a standard
USB drive.

Anybody have a solution?

Is there some documentation of what changes from 14.2
were necessary and the best workaroung.

I got rsync to work by:

alias rsync="/usr/bin/rsync --protcol=3.1.3"

Without this it seems to regard separate drives on the
same system as being remote requiring ssh comunication.
That's my guess because it screws around with the
known_hosts file.
