Hard disk first read and write too slow problem

The kernel prints as follows:

Modification Method:

The test voltage is normal, that is, the first read and write is slow, with "USB 2-1: RESET high-speed USB device number 4 using EHCI-BRCM" printing.

The problem does not exist after updating the hard drive adapter board
