I have a USB memory stick that used to work perfectly fine, but then I made a mistake while trying to install a disk image onto it and now no computer recognizes that it is a memory drive. It doesn't mount, and fdisk doesn't recognize it. However lsusb recognizes it. Output of fdisk -l

It may be important to note that I know that the usb port works, and that the same problem occurs on other computers and other operating systems.

Best Answer
Sometimes writing ISO files junks my usbs. It seems to happen most when I try to partition space for persistent storage. What i normally do is power cycle then open gparted and format the usb.
then
