Looking for a USB Device That Can Be Accessed Over the Network
Asked by

I'm working with an industrial computer system where users need to connect a USB drive to upload files due to regulatory processes. While I know there are ways to add files via SFTP, the USB step is mandatory sometimes. I want to have more control over users' ability to add files to USB devices and am looking for a solution that allows files to be uploaded via means like HTTPS, SFTP, or SMB, but still presents itself as a USB storage device to the industrial system. Has anyone come across such a device or have tips on how to search for it effectively?

Have you considered using a custom Raspberry Pi Zero W? It has a USB gadget mode that could potentially be adapted to fit your needs.

What you're looking for theoretically exists and could be done in Linux. Although I haven't seen a complete solution, I've noticed attempts that work along the lines of connecting the device's USB to a storage system over Ethernet for PC access.

You might want to check out the AnywhereUSB from Digi. It's a nice option for remote USB connections but does require additional software or drivers on the industrial computer, which might not meet your needs for plug-and-play functionality.

I've dealt with AnywhereUSB and can confirm it needs drivers. I also used Crestron units which have a couple of options that might do the job. They work reasonably well, but setup can be tricky, especially with larger systems.

I've found a device that fits your requirements somewhat! It's a PiKVM that can emulate storage devices. You do need to unmount the drive from the host to access it, but it could be a potential solution. Just look for Linux-based KVMs that support mass storage functionality.
