使用ccs开发msp430时出现了下面的错误：
MSP430: Error initializing emulator: One of the connected MSP-FETs / eZ-FETs debuggers needs recovery. Select 'Recover' to start the recovery process. Note: Only one MSP-FET / eZ-FET debugger can be connected to your system during recovery.
MSP430: Error: MSP-FET / eZ-FET recovery failed
插上msp430f5529会显示有U盘接入，设备管理器找不到任何和MSP相关的端口
