I want to setup a Raspberry PI so that a thumb drive at say /dev/sdb1/
will also show up at /dev/sdb2
so that a male-male USB cable can then be plugged into dev/sdb2/
and then into my car stereo USB to be read as a USB drive.
Put another way, I want my cars USB slot to be able to be plugged into USB2 and read USB1(thumbdrive)
Is this possible? How would I do it?
