Linux USB port as a 'flash disk'
Is there a way to present a path or other block device to a USB port on a Linux server then have that port connected to a USB port of another device (ie USB to USB) and have it look like a flash disk?
I can plug a USB flash disk to a router just fine. But if I wanted a device to access a path off of another device int he absence of NFS or CIFS capability, that would be handy.
In other words, anyway to assign storage to a USB port in Linux? It would be akin to something like SAN with a target and source just with USB.
