My K3, KPA500, KAT500, two USB soundcards and an SDR are all
cabled together and playing well. I would like to upgrade the firmware
in all 3 K line devices. Is it necessary to completely or partially
remove cables before attaching my computer via USB - serial port cable

Larry,
You *should* be able to do the firmware upgrades with the cabling in place.
Of course, if you have any difficulty, the first order of
troubleshooting is to isolate the gear that is producing problems.

I have used a four-port USB to Serial Adapter (purchased on Amazon, from
Gearmo), along with two KXSER cables for the 9-pin DIN to 3.5mm
There is also a Siig brand usb to serial port unit available in 2, 4 or
8 serial ports that is far less expensive and works very well.

That's about twice what I paid for an Edgeport 8, new in box, on eBay.
One advantage of the four port Gearmo (for under $50) is that it terminates in
male DB9 plugs that go right onto the back of the P3 and KPA500, no added RS232
jumpers needed. I did need KXSER jumpers for the 3.5mm Elecraft
What exactly is the function of this device? Does it give you 8 separate serial
ports? Or is it just a hub? Is it somehow different from plugging 8
USB-to-serial cables into a computer?
Thanks!

You only plug one USB cable into the computer and the device creates x
number of virtual serial ports.
Here's another one that has 4 serial outlets
Yes. Exactly. 8 separate serial ports fed from a single USB port.
There are many different types of these devices. The one I use has one
USB connector and 4 cables with DB9 connectors already attached - which
makes it very convenient to hook up everything requiring a serial port
with one
