Hi vltcl
Since you have access to a Linux setup, we'll use it to blank your USB drive:
To find your device, run this:
tc@E310:~$ fdisk -l | grep -v loop | grep -i "Disk /dev/s"
Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Disk /dev/sdb: 465.8 GiB, 500107862016 bytes, 976773168 sectors
tc@E310:~$
Then plug in your device and run it again:
tc@E310:~$ fdisk -l | grep -v loop | grep -i "Disk /dev/s"
Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Disk /dev/sdb: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Disk /dev/sdg: 959.5 MiB, 1006108672 bytes, 1965056 sectors
tc@E310:~$
Your device will show up as an additional entry in the list, /dev/sdg in this example.
dd if=/dev/zero of=/dev/YourDevice bs=512 count=1
Be extremely careful with this command. You will need to replace /dev/YourDevice with the /dev/ assigned to your device.
Now go back to windows and format a FAT partition.
