# USB Service Development
## When to Use
In Host mode, you can obtain the list of connected USB devices, enable or disable the devices, manage device access permissions, and perform data transfer or control transfer.
## APIs
## Available APIs
The USB service provides the following functions: query of USB device list, bulk data transfer, control transfer, and access permission management.
The following table lists the USB APIs currently available. For details, see the [API Reference](../reference/apis/js-apis-usbManager.md).
**Table 1** Open USB APIs
**Table 1** Open USB APIs
| API | Description |
| Name | Description |
| ------------------------------------------------------------ | ------------------------------------------------------------ |
| hasRight(deviceName: string): boolean | Checks whether the user has the device access permissions. |
| requestRight(deviceName: string): Promise\<boolean> | Requests the temporary permission for a given application to access the USB device. This API uses a promise to return the result. |
| connectDevice(device: USBDevice): Readonly\<USBDevicePipe> | Connects to the USB device based on the device list returned by `getDevices()`. |
| getDevices(): Array<Readonly\<USBDevice>> | Obtains the list of USB devices connected to the USB host. If no USB device is connected, an empty list is returned. |
| setConfiguration(pipe: USBDevicePipe, config: USBConfiguration): number | Sets the USB device configuration. |
| setInterface(pipe: USBDevicePipe, iface: USBInterface): number | Sets a USB interface. |
| claimInterface(pipe: USBDevicePipe, iface: USBInterface, force ?: boolean): number | Claims a USB interface. |
| bulkTransfer(pipe: USBDevicePipe, endpoint: USBEndpoint, buffer: Uint8Array, timeout ?: number): Promise\<number> | Performs bulk transfer. |

## How to Develop
You can set a USB device as the USB host to connect to other USB devices for data transfer. The development procedure is as follows:
1. Obtain the USB device list.
```js
// Import the USB API package.
import usb from '@ohos.usbManager';
// Obtain the USB device list.
let deviceList = usb.getDevices();
/*
Example deviceList structure
[
{
name: "1-1",
serial: "",
manufacturerName: "",
productName: "",
version: "",
vendorId: 7531,
productId: 2,
clazz: 9,
subClass: 0,
protocol: 1,
devAddress: 1,
busNum: 1,
configs: [
{
id: 1,
attributes: 224,
isRemoteWakeup: true,
isSelfPowered: true,
maxPower: 0,
name: "1-1",
interfaces: [
{
id: 0,
protocol: 0,
clazz: 9,
subClass: 0,
alternateSetting: 0,
name: "1-1",
endpoints: [
{
address: 129,
attributes: 3,
interval: 12,
maxPacketSize: 4,
direction: 128,
number: 1,
type: 3,
interfaceId: 0,
}
]
}
]
}
]
}
]
*/
```

let deviceList = usb.getDevices();
/*

direction: 128,
number: 1,
type: 3,
interfaceId: 0,
}
]
}
]
}
]
}
]
*/
```
2. Obtain the device operation permissions.
```js
let deviceName = deviceList[0].name;
// Request the permissions to operate a specified device.
usb.requestRight(deviceName).then(hasRight => {
console.info("usb device request right result: " + hasRight);
}).catch(error => {
console.info("usb device request right failed : " + error);
});
```
```js
let deviceName = deviceList[0].name;
// Request the permissions to operate a specified device.
usb.requestRight(deviceName).then(hasRight => {
console.info("usb device request right result: " + hasRight);
}).catch(error => {
console.info("usb device request right failed : " + error);
});
```
3. Open the device.
```js
// Open the device, and obtain the USB device pipe for data transfer.
let interface1 = deviceList[0].configs[0].interfaces[0];
/*
Claim the corresponding interface from deviceList.
interface1 must be one present in the device configuration.
*/
usb.claimInterface(pipe, interface1, true);
```
```js
// Open the device, and obtain the USB device pipe for data transfer.
let pipe = usb.connectDevice(deviceList[0]);
let interface1 = deviceList[0].configs[0].interfaces[0];
/*
Claim the corresponding interface from **deviceList**.
interface1 must be one present in the device configuration.
*/
usb.claimInterface(pipe, interface1, true);
```
4. Perform data transfer.
```js
/*
```js
/*
Read data. Select the corresponding RX endpoint from deviceList for data transfer.
(endpoint.direction == 0x80); dataUint8Array indicates the data to read. The data type is Uint8Array.
*/
let inEndpoint = interface1.endpoints[2];
let outEndpoint = interface1.endpoints[1];
let dataUint8Array = new Uint8Array(1024);
usb.bulkTransfer(pipe, inEndpoint, dataUint8Array, 15000).then(dataLength => {
if (dataLength >= 0) {
console.info("usb readData result Length : " + dataLength);
} else {
console.info("usb readData failed : " + dataLength);
}
}).catch(error => {
console.info("usb readData error : " + JSON.stringify(error));
});
// Send data. Select the corresponding TX endpoint from deviceList for data transfer. (endpoint.direction == 0)
usb.bulkTransfer(pipe, outEndpoint, dataUint8Array, 15000).then(dataLength => {
if (dataLength >= 0) {
console.info("usb writeData result write length : " + dataLength);
} else {
console.info("writeData failed");
}
}).catch(error => {
console.info("usb writeData error : " + JSON.stringify(error));
});
```
5. Release the USB interface, and close the USB device.
```js
usb.releaseInterface(pipe, interface);
usb.closePipe(pipe);
```

let inEndpoint = interface1.endpoints[2];
let outEndpoint = interface1.endpoints[1];
let dataUint8Array = new Uint8Array(1024);
usb.bulkTransfer(pipe, inEndpoint, dataUint8Array, 15000).then(dataLength => {
if (dataLength >= 0) {
console.info("usb readData result Length : " + dataLength);
} else {

} else {
console.info("writeData failed");
}
}).catch(error => {
console.info("usb writeData error : " + JSON.stringify(error));
});
```
5. Release the USB interface, and close the USB device.

You are advised not to call the [requestSuspendDelay()](../reference/apis/js-apis-resourceschedule-backgroundTaskManager.md#backgroundtaskmanagerrequestsuspenddelay) method to apply for delayed suspension after the application is running in the background. Instead, you need to call this interface to declare the execution time of the extended application to the system before performing any time-consuming operation. It is recommended that an application calls [requestSuspendDelay()](../reference/apis/js-apis-resourceschedule-backgroundTaskManager.md#backgroundtaskmanagerrequestsuspenddelay) when it is running in the foreground, so as not to affect the transient task quota of the application.
An application can obtain the remaining duration before being suspended by calling [getRemainingDelayTime()](../reference/apis/js-apis-resourceschedule-backgroundTaskManager.md#backgroundtaskmanagergetremainingdelaytimecallback). Each application has a daily time quota for transient tasks. Therefore, after the time-consuming task finishes execution, the application should call [cancelSuspendDelay()](../reference/apis/js-apis-resourceschedule-backgroundTaskManager.md#backgroundtaskmanagercancelsuspenddelay) to cancel the transient task in a timely manner.

Typical time-consuming tasks include saving status data to the local database, opening and processing a large file, and synchronizing data to the cloud server.
