Basically there are 2 flavours of workaround (tested successfully for 2 weeks so far): The reason for this seems to be incomplete compatibility (better than complete incompatibility) between Google’s IMAP implementation and Apple’s (great?) expectations of how it should be done. If you are using a Google-Account on your iOS device (up to version 11), you might -at least occasionally- encounter the problem that it is deactivated/greyed out/disabled in the Mail app and will open up only after a while or several restarts of the Mail app and/or the phone. Go to Disk Management and remove all volumes from the USB stick. The USB media key MUST NOT BE FORMATTED - at all. The information in bold type is the wrong part! Obtain a formatted USB media key and place it in the USB port.Those might be the solution for other cases, for mine it was much simpler. Generally the internet recommends all kinds of things: readonly flags removed (diskpart), PNY UFIX-II to UFIX-V, use another USB stick, etc. Google it and you shall be given - maybe.

I tried that several times with multiple different sticks, but no dice. The utility was constantly reporting “Device Media is write-protected” when I clicked the Start button thus confirming it could format the stick. as I have been for half an hour to flash the newest BIOS/Firmware to my G6 and G7 servers (Spectre variant 4, SP99328 / SP99323), here might be a solution for you. If you have failed (on Windows 10) to create HPP SPP bootable USB media keys via the HPEUSB.EXE utility included in said SPP (with ROMPAQ.exe etc. Incorrect instructions for HPE USB utility
