Shalom,

Plug the device in.

fdisk -l

try a manual mount

mount -t vfat

As a security measure auto detect of USB can be blocked as can any detection of USB, though that is not an OS default.

Hi,

Do you have more than one USB port on the laptop? If so, does the same error occur on other USB ports on that laptop?
