CLK3 , not from the USB chip, comes from VCO o/p of U3, a 74HCT4046 , whose
sig in comes from U29 an 04 inverter whose input comes from pin33 of the
CPLD functional blocks, which is firmly stuck logic H so vicious circle of
inactivity.
Incidently TP4 of 8 is the only one with any activity on , one of the approx
22MHz clocks.
Will have to leave exploring this for a while and get back to bread and
butter work, but any suggestions for hardware checking in the meantime,
welcome

Well I've sent the following but I somehow doubt anything useful in reply


Event Ezbus, fails to boot
Just the message "Becoming Ezbus..." and nothing else, no response to
anything. I'm an electronic engineer so if an internal physical reset is all
that is required, no problem. I Have tried all easy 2 and 3 button push
"factory reset" at power-up combinations.

worse than that
techsupportATevent1.com
just bounces emails with cryptic messages.
I used 2 totally different accounts

Maybe they just changed their address, found this on the web:

http://event1.com/contact.php

they also have a different email on their support page.

I'd found a small number of references to techsupport in front of the @ on
that varriant , and will try that
