BG95-M1 QFDWL problem when connecting USB 1.0 device

BG95-M1 is connecting to MCU with USB 1.0. We downloaded 2 MB file to UFS by using AT+QFDWL, however, the process may stop after the download size is around 5 KB to 200KB and we did not get +QFDWL : response. We have tested the same code in EG91 module and it works well. Please advise.
