/media/usb - "The path is not writeable"

[ubiquitous42]

Hardware Setup
Ender 3 Pro with SKR Mini v2.0

Describe the problem
I am able to successfully flash the firmware using an SD card inserted directly into the printer, but despite my best efforts to set up usbmount, I am unable to update the firmware via Firmware Updater.
