!!! question "Since sing-box 1.14.0"
# USB/IP Server
USB/IP Server service exports local USB devices over [USB/IP](https://usbip.sourceforge.net/),
to be imported by the [USB/IP Client](/configuration/service/usbip-client/) or a standard USB/IP
client.
Available on Linux, Windows, and macOS (macOS requires a build with CGO, and exporting devices
requires disabling System Integrity Protection). Not available on iOS.
### Structure
```json
{
"type": "usbip-server",
... // Listen Fields
"provider": "",
"devices": []
}
```
!!! info "Difference from the official USB/IP protocol"
sing-box uses [sing-usbip](https://github.com/SagerNet/sing-usbip), which uses an additional
set of protocols to support enhancements such as hotplug, while remaining interoperable with
the standard USB/IP protocol.
### Listen Fields
See [Listen Fields](/configuration/shared/listen/) for details.
`listen_port` defaults to `3240`.
### Fields
#### provider
The device source provider.
- `default`: Exports the local devices matched by `devices`. The default value.
- `dynamic`: Devices are provided at runtime through a [sing-box API](/configuration/service/api/)
client instead of from configuration, on supported platforms: the sing-box graphical clients on
[macOS](/clients/apple/) and [Android](/clients/android/), and Chromium-based browsers with
[sing-box Dashboard](https://github.com/SagerNet/sing-box-dashboard).
!!! quote ""
The `default` provider is only supported when running directly via the CLI on Linux, Windows,
and macOS, and requires elevated privileges.
#### devices
==Required== with the `default` provider.
List of device matches selecting which local USB devices to export.
Object format:
```json
{
"bus_id": "",
"vendor_id": 0,
"product_id": 0,
"serial": ""
}
```
Object fields:
- `bus_id`: USB bus ID, e.g. `1-2`.
- `vendor_id`: USB vendor ID, as a number.
- `product_id`: USB product ID, as a number.
- `serial`: Device serial number.
Within one object, all specified fields must match; multiple objects are combined as a union. At
least one field is required.
