I need to access a USB device from another computer on my home network without paying for extra software. I tried a couple of free methods, but the device either disconnects or isn’t detected correctly. I’m looking for a reliable free way to share USB over network on Windows, and I need help figuring out what actually works.
Free USB over network on Windows is rough. Windows does not natively share raw USB devices over LAN in a clean way. A lot of ‘free’ tools break on printers, dongles, scanners, and stuff with picky drivers.
What usually works, for free:
-
USB over IP on Linux server
If you have an old PC or Raspberry Pi, use usbip. Solid for many devices. Less fun on Windows clients. Setup takes time. -
VirtualHere trial
Good test tool. Free version is limited. Fine for one device in some cases, but not a long-term answer for most people. -
Share the function, not the USB
Printer, use network printing.
Drive, use SMB share.
Webcam, use webcam software.
This is more stable than forwarding the whole USB device.
On Windows-only, fully free and reliable options are slim. That’s the annoying part. If the device keeps dropping, it’s often power management, bad drivers, or the free app not handling USB timing well.
Try this first.
Disable USB selective suspend.
Turn off ‘Allow the computer to turn off this device’ in Device Manager.
Use a powered USB hub if the device draws extra power.
If you need it to work with less pain, USB Network Gate is one of the better options people end up using. Not free, but stable. This video shows the setup steps well: watch how to share USB devices over your network
Best search phrase for this topic:
Free USB over network solution for Windows, share USB device over LAN with stable remote access
If you post the exact device type, I can point you to the least-bad method.

Honestly, if you want actually free, the best move is to stop thinking “share the USB device” and start thinking “remote into the PC that already has the USB plugged in.”
That sounds like a cop-out, but for a lot of home setups it works way better than flaky USB forwarding. If the device only needs an app on the host PC, use Remote Desktop, Chrome Remote Desktop, AnyDesk free tier, whatever, and control it there. No weird driver passthrough, no random disconnects, less hair-pulling. I kinda disagree with @cazadordeestrellas on one point: sometimes trying to force true USB-over-LAN at home is just not worth the pain unless the device absolutely must enumerate locally on the second machine.
If you do need the second PC to see it like it’s physically attached, then the free options get ugly fast. Stuff like license dongles, scanners, specialty serial adapters, and audio interfaces are super picky. That’s usually where “free” turns into “why is this broken agian?”
A few things people forget to test:
- use the shortest USB cable possible
- avoid front panel USB ports
- put both PCs on wired ethernet, not Wi-Fi
- disable antivirus/firewall temporarily to test discovery
- make sure the device is not being grabbed by vendor software on the host PC first
- check if the device has its own network mode or Ethernet print/server utility
If you want the least annoying dedicated option, USB Network Gate is one of the few that tends to just work across Windows PCs. If you want to try it, grab the latest USB Network Gate download for sharing USB devices over a network.
Post the exact USB device model. That matters a lot more than people think.
I’d split this by device type, because “USB over network” is not one problem.
- Printers / some scanners: don’t use USB sharing at all. Use the printer/scanner’s built-in network setup, or plug it into a router/NAS print server if supported.
- Storage drives: share the folder over SMB. Way more stable than forwarding raw USB.
- Webcams, audio interfaces, license dongles, weird adapters: this is where free tools usually fall apart.
Small disagreement with @cazadordeestrellas: on Linux, USB/IP is not always terrible. If both machines are fairly plain Windows/Linux boxes and the device is simple, it can work. But for consumer home setups, driver issues are usually the brick wall.
If you want one more free-ish angle before paying for anything, try:
- plug the USB device into a Raspberry Pi or spare Linux box
- expose it with usbip
- attach from the other PC
That avoids some Windows-host weirdness. Still not magic though.
If you give up on pure free, USB Network Gate is the usual “fine, just work” option.
Pros:
- easy setup
- device appears locally on the client
- better compatibility than most free hacks
Cons:
- not free long term
- some real-time devices can still be picky
- performance depends heavily on network quality
So the real answer is: use the device’s native network feature if it has one, use file/app sharing if that fits, try USB/IP only for tinkering, and save true USB forwarding for cases that absolutely need it.
