Hey All,

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.

Cheers,

usb ports are mostly not symmetrical. Devices have different connectors than hosts. For example, hosts provide power and devices consume power. Do you have a computer with a device port?

No, only standard USB ports provided by the MOBO.

I know I can cut power to the USB ports using the proc filesystem and manipulate many other things on them so curious if it could be set to point to a block device instead.

Power and physical connector hardware are one factor but desktops and laptops typically only have USB host controllers and can not be configured as a device. Many single board computers have both or an OTG port which you could use the USB gadget mass storage module. I personally have not tried doing this yet.

Mount the usb as an iscsi and it will then be available to remote systems.

What you actually asked was to use a usb in one system and have it attached to another system as a usb. While that may be possible in a round about way such as a virtual machine. Possibly some windows set ups can do that too.
