"Not Usable" as a status means something isn't working in the WCCP protocol.
a "term mon", "debug ip wccp packets" and "debug ip wccp events" will give
you some clue as to what is going wrong.
as a guess, i'd say that you're getting "wrong protocol" or "bad packet"
messages.
it is probably likely that your 75xx is running an IOS release where WCCPv1
is default and 12.1E for the cat6k has WCCPv2 as default.
squid (publically) only supports WCCPv2 - so you'll need "ip wccp version
1" as a global config command if this is the case.

WCCP supports the concept of the cache being multiple hops away, using a
GRE tunnel between the router & cache.
it is likely one of the many bugs in squid's WCCP implementation.

not sure what you mean here????
redirected packets encapsulated inside a GRE tunnel typically have:
- an additional 20-byte ip header on the front (GRE encapsulation)
- an additional 4-byte WCCP header.
whatever the size of the UDP port 2048 (control-plane) WCCP messages is not
relevant.
