TMDSEMU560V2STM-UE: Purchase a batch of TMDSEMU560V2STM-UE emulators

Part Number: TMDSEMU560V2STM-UE
Purchase a batch of TMDSEMU560V2STM-UE emulators, two of which have the following problems:
1. Serial number :SB45958 After connecting to the computer, the USB and mode lights were not on, and the Blackhawk device could not be identified. If you switch to a normal XDS, it could be identified normally, so it must be burnt out.
2. Product serial number: SB46012 Description: After test Connect, operation Debug cannot be loaded. Now two products need repair and testing, please help to deal with it, thank you
