Linux never disconnects anything by itself, but something we do makes
your device to roll over and play dead. Please send me a usbmon trace
(see /usr/share/doc/kernel-doc-2.6.22/Documentation/usb/usbmon.txt).
Also, I'd like to see /proc/bus/usb/devices (please disable sierra
driver by renaming or blacklisting it temporarily so it does not
kill the device before you can capture the devices file). I'll poke
the upstream about it we can put together an error case.
