QmiThreadSendQMITimeout pthread_cond_timeout_np=110, errno: 10

Dear Quectel Team,

We designed a board with using EC25-EC module and have connected it,over USB Interface, to our another board which runs Linux OS. In some cases especially if we plug a Wifi module to our system over an another USB connector, after a couple of time, we are getting below error codes. After these errors occur, then the system losses IP at wwan. Can you please specify that what is going wrong with the module?
