My ST-Link/V2-1 doesn't work after upgrading FW

[OChen.1]

Hi!

My ST-Link/V2-1 of NUCLEO-F302R8 doesn't work after upgrading ST-Link/V2-1's FW to latest version.

Using lsusb it seems appear:

Bus 001 Device 008: ID 0483:374b STMicroelectronics ST-LINK/V2.1

However, STLinkUpgrader says something wrong with it:Could anyone advise how I should do to solve this issue?

This issue seems to be caused by the bad contact of my USB cable. If I tweak the USB connector after connecting it to a PC, then LED LD1 will turn from red to green, and the connection from STM32CubeIDE to Nucleo-STM32F302R8 become OK.

Therefore I guess the updated FW in its on board STLink/V2-1 might be OK.
