I am trying to use MSP_EXP430FR5994 Launchpad kit for SD read/write operation. Now the kit is not detected by the PC, no communication ports are available(it is showing that the USB device not recognized). The red led(LED101) is glowing once USB cable is connected to the PC and the green led(LED102) is blinking in irregular interval. i have reinstalled the FET-Z driver also. Please help me solve the problem.
