Hi George, Here's the full log and it seems usbserial support is getting registered.

One other possibility - I don’t see the usbserial support being registered in Amit’s log. Could it be that you have got the relevant usbserial detection support enabled on your Linux box …. George

Amit,
The 90 seconds delay is key here. In "install bootloader" mode, you must make sure to start the USB download process within 90 seconds of powering up hikey.
The log you attached makes sense to me. Everything are reasonable. Here for your reference, is on mine board and PC. In this case, I should run 'hisi-idt.py' before [14495.204951].
On Amit's board the logs do look very similar but the disconnect happens
after half a second (rather than 90 seconds). I think that is what leads to a guess conclusion there is a hardware fault.
