Re: No message in linux kernel John Vidler Sun Feb 26 12:00:36 2012

USB A to USB A is a non-standard, out of spec. cable. Be very careful with
plugging them into anything as some combinations can damage the controllers.
USB A-types should always be connected to the master, and B-type to the
slave, (B-downstream), any other connection type is inviting disaster.

My suggestion would be to use a USB-to-ethernet adapter from the tablet,
and plug the ethernet cable between that and the laptop's ethernet port,
(you may need a crossover cable, it depends on the laptop age and card
ability).
All of this is assuming the tablet has a usb-ethernet driver, of course.

Good luck!

-John.
