CH32F205 USBFS配置为Device 但是不管如何转发描述符到USB端点都是让鼠标往右移动

CH32F205 两个usb 一个配置为主机一个配置为HID设备主机接收HID设备数据然后通过从机USB端口转发给PC

这是主函数设置

int main( void )

{

/* Initialize system configuration */

Delay_Init( );

USART_Printf_Init( 115200 );

DUG_PRINTF( "SystemClk:%d\r\n", SystemCoreClock );

DUG_PRINTF( "USB HOST KM Test\r\n" );

/* Initialize TIM3 */

TIM3_Init( 9, SystemCoreClock / 10000 - 1 );

DUG_PRINTF( "TIM3 Init OK!\r\n" );

/* Initialize USBHS host */

/* Note: Only CH32F205/CH32F207 support USB high-speed port. */

#if DEF_USBHS_PORT_EN

DUG_PRINTF( "USBHS Host Init\r\n" );

USBHS_RCC_Init( );

USBHS_Host_Init( ENABLE );

memset( &RootHubDev[ DEF_USBHS_PORT_INDEX ].bStatus, 0, sizeof( ROOT_HUB_DEVICE ) );

memset( &HostCtl[ DEF_USBHS_PORT_INDEX * DEF_ONE_USB_SUP_DEV_TOTAL ].InterfaceNum, 0, DEF_ONE_USB_SUP_DEV_TOTAL * sizeof( HOST_CTL ) );

#endif

/* Initialize USBFS host */

#if DEF_USBFS_PORT_EN

DUG_PRINTF( "USBFS Host Init\r\n" );

// USBFS_RCC_Init( );

// USBFS_Host_Init( ENABLE );

USBFS_RCC_Init( );

USBFS_Device_Init( ENABLE );

DUG_PRINTF(" < - USB DEVCIE INIT OK - > \r\n");

memset( &RootHubDev[ DEF_USBFS_PORT_INDEX ].bStatus, 0, sizeof( ROOT_HUB_DEVICE ) );

memset( &HostCtl[ DEF_USBFS_PORT_INDEX * DEF_ONE_USB_SUP_DEV_TOTAL ].InterfaceNum, 0, DEF_ONE_USB_SUP_DEV_TOTAL * sizeof( HOST_CTL ) );

#endif

while( 1 )

{

USBH_MainDeal( );

}

}

这是USBH_MainDeal 函数里获取到描述符的部分不管我接入键盘还是鼠标都是鼠标一直往右移动

/* Get the data of the HID device connected to the USB host port */

for( usb_port = 0; usb_port < DEF_TOTAL_ROOT_HUB; usb_port++ )

{

if( RootHubDev[ usb_port ].bStatus >= ROOT_DEV_SUCCESS )

{

index = RootHubDev[ usb_port ].DeviceIndex;

if( RootHubDev[ usb_port ].bType == USB_DEV_CLASS_HID )

{

for( intf_num = 0; intf_num < HostCtl[ index ].InterfaceNum; intf_num++ )

{

for( in_num = 0; in_num < HostCtl[ index ].Interface[ intf_num ].InEndpNum; in_num++ )

{

/* Get endpoint data based on the interval time of the device */

if( HostCtl[ index ].Interface[ intf_num ].InEndpTimeCount[ in_num ] >= HostCtl[ index ].Interface[ intf_num ].InEndpInterval[ in_num ] )

{

HostCtl[ index ].Interface[ intf_num ].InEndpTimeCount[ in_num ] %= HostCtl[ index ].Interface[ intf_num ].InEndpInterval[ in_num ];

/* Get endpoint data */

s = USBH_GetHidData( usb_port, index, intf_num, in_num, Com_Buf, &len );

if( s == ERR_SUCCESS )

{

#if DEF_DEBUG_PRINTF

for( i = 0; i < len; i++ )

{

DUG_PRINTF( "%02x ", Com_Buf[ i ] );

}

DUG_PRINTF( "\r\n" );

#endif

int8_t x_move = (int8_t)Com_Buf[1]; // X 位移

int8_t y_move = (int8_t)Com_Buf[2]; // Y 位移

int8_t wheel_move = (int8_t)Com_Buf[3]; // 滚轮位移

DUG_PRINTF("Mouse Move: X=%d, Y=%d, Wheel=%d\r\n", x_move, y_move, wheel_move);

// 上传数据到端点

DUG_PRINTF("Uploading Data: %02x %02x %02x %02x\r\n", Com_Buf[0], Com_Buf[1], Com_Buf[2], Com_Buf[3]);

uint8_t report_len = 4; // HID 描述符定义了 4 字节

if (USBFS_Endp_DataUp(endp, Com_Buf, report_len, DEF_UEP_DMA_LOAD) == READY) {

DUG_PRINTF("Mouse Data Uploaded to Endpoint %d\r\n", endp);

} else {

DUG_PRINTF("Mouse Data Upload Failed!\r\n");

然后串口的打印数据一直是往一个方向累加
