You can't do anything with it until it's detected properly.
Try it in a drectly connected to the mboard USB port.
If that doesn't help, it's likely you have damaged the partition table info on it by unplugging it at the wrong time. . Windows can format a flash drive, but it has to be seeing the drive properly when it does - it can't delete the partition and make new one due to Microsoft's wishes. (The same probably applies for the HP format program.)
You can fix the problem if the flash drive itself is not damaged.
