Hi Minas, Thanks for your reply!

It doesn't seem to make a difference with the patch applied.

I enabled the dwc2 debug logging option in menuconfig, 
and captured the logs when I plug in, disconnect and re-plug in. 

The link to log file is
https://drive.google.com/file/d/1ID3bDp4NA6vSXf4AqN8w2WiDhaFbnb59/view?usp=sharing 

At [   32.964469] the gadget config was bound to the device;
At [   38.002792] the device was plugged to a PC;
At roughly [   43.063762] the device was disconnected; at [   45.640378] the
device was re-plugged.

After a short period of time the kernel freezes, no more logs can be output.
