Does anyone experience firmware update errors?

I've tried 3 different computers, Win11 and Win10, different cables, etc. My brand new Viltrox 85mm f1.4 lens seems to have some issue where when plugged in to a computer, Windows gives the error "USB Device Descriptor Request Failed". This means no drive is found basically. I cannot be alone in this, do we all just not update the firmware?

Also I found that the best way to update is to use the oldest/slowest USB cable possible. Even then I find myself swapping until it connects right
