What about "fastboot devices". If that doesn't respond quickly with the device serial number then I suggest updating your fastboot drivers. I am assuming that the device is in fastboot mode, of course.

I always use that command to test the fastboot connection before using any more serious fastboot commands.

How to upload fastboot drivers

Since I use Mac and Linux I don't generally have to worry about this stuff, but a quick Google search brought up this link from htcdev.com that looks promising: https://www.htcdev.com/process/legal_fastboot_win

Yeah, adb is not used for unlocking your bootloader--that's what the fastboot utility is for.

adb is and can be used when normal Android is booted-up or you have a custom recovery installed (or when your sideloading an OTA from the stock recovery).

Put your device in fastboot/bootloader mode by powering it down, then press the power and volume-down buttons at the same time to boot into fastboot/bootloader mode).
