So I have configured to use blazer_usb driver. However NUT behaves incorrectly after switching blazer_usb. System is being halted upon booted up.

It might be possible, but the correct solution would be to fix the current drivers. (Note that blazer_usb has been superseded by nutdrv_qx in later versions of NUT.)

I am curious whether the UPS is always sending FSD, or if the bit controlling FSD is inverted.

Does the UPS have a "force shutdown" feature? If so, here's how to test:

1) Power down, and disconnect the UPS USB cable from the computer.
2) Power up the computer attached to a different UPS or wall outlet
3) Turn the UPS on
4) Kill the upsmon process (this will prevent automatic shutdown)
5) Plug the UPS USB cable back in
6) Turn the UPS off, and watch "upsc ups.status"

If the "FSD" indication disappears, then the bit is inverted, otherwise it needs to be ignored.
