mounting /dev/sdb1 on /tmp/usb_stick failed: Invalid argument (6 replies)

I have a pink POGO-E02. I haven't used it except I tried to install Linux years ago. Now I want to try running "homeassistant" (HomeAssistant.io).

Only port 22 is open and I finally guessed the root password I entered. I am trying to mount a USB drive.

mount /dev/sdb1 /tmp/usb_stick: mounting /dev/sdb1 on /tmp/usb_stick failed: Invalid argument

I just formatted it on my Linux PC.

fdisk -l

/dev/sdb1 1 584 3926016 c Win95 FAT32 (LBA)

ls -l /

Why can't I mount the USB drive? Thanks

P.S. I can install a serial connection if necessary.
