44B0与CH375调试时,对威刚USB2.0支持热插拔可以,但是我换其它好几款U盘(TCL,郎科)时,中断不能触发,而且我不能用CH375RESET软件复位,我把U盘拔下时,还是提示81:硬件错误。斑竹求救!!! while ( CH375DiskStatus != DISK_CONNECT ) { Uart_Printf("\nCH375-USB Host For S3C44B0X\n"); mDelaymS( 300 ); CH375Reset(); mDelaymS( 600 ); i = CH375LibInit( ); /* 初始化CH375程序库和CH375芯片,操作成功返回0 */ mDelaymS( 600 ); if (i==0) Uart_Printf("\nCH375_Init完成!!\n"); else Uart_Printf( "Error: %02X\n", (INT16U)i ); /* 显示错误 */ mDelaymS( 5000 ); }
