DS90UB949-Q1: EVM is not recognized in "ALP".

Part Number: DS90UB949-Q1
Other Parts Discussed in Thread: ALP, USB2ANY

EVM is not recognized in "ALP".

step1. Not recognized by "ALP".
step2. I checked that the USB was not recognized in "Device Manager". (Check the USB port as well)
step3. The board is normally connected.
step4. I tried to update the firmware by installing the MSP430 you answered, but it says "no device connected".
step5. If you press and hold the s3 button, "unknown usb device (device descriptor request failed)" is displayed in the device manager.
