Firmware for MiniView G-CSIO4U 4-port USB KVM switch??

[BeartoothHbsk]

	For the last several years, I have been running the same four PCs 
behind the same KVM switch, with the same keyboard, mouse, and monitor 
(an HP w2207 which is marginal for the hardware of the older two), with 
several releases of Fedora.

	Now suddenly (beginning iirc with, certainly after, installation 
of F12) everything related to the display keeps going exponentially worse.

	Discussion with a local friend who speaks hardware (as I do not, 
alas!), reached a suggestion to try updating the firmware.

	Googling got me to a stub of what had been Fedora Portal (and had 
apparently had something specifically about firmware for this switch), 
with a recommendation to come here.

	Before I go into a tedious tale of woe, does anybody know 
anything specifically about the firmware on this switch, and how to 
update it for Fedora??

I have precious (very precious!) little idea where up is.
