RFSoC4x2 frequent disconnection

Hello, I am using RFSoC4x2, PYNQ version 3.0.1.
The board is connected to PC with micro b usb.
When I boot the board, it works well, but shortly after, the PC pops up a message saying that the USB connection is failed. This never happens when I work with the other devices using the same port of the PC, so I guess the problem is on the board.
Can this be a soldering problem? And if so, how can i check it? Am I allowed to use multimeter on the board?
Thank you for reading.

Have you tried connecting the board to a network via the eternet port? You could then access the board by connecting your computer to that same network
