just to clarify about the usb port. you can change the port in startup settings. at some time before v5.4.4 you may have set it to port 1 (the top one) port 0 is the bottom one.
on v5.2.0 force cios defaulted to off which means it uses ios58
v5.40+ force cios defaults to on, but if you already have wiiflow save set with force cios off then its still off and uses ios58
if you delete the wiiflow save file v5.4.0+ will set force cios on. wiiflow uses cios 249 by default.
so with ios 58 you can use either port.
with cios 249 it depends on what cios you have installed in slot 249.
my understanding is d2x v9 and v10 can use either usb port.
back in the old days you could only use port 0 unless you were using a hermes cios.
as for devolution. I really don't know. i think i'm using an older version than you maybe that's why it works for me. or maybe its because i use a sd card and my gc games are on USB. and you only use usb.
also if you did use sd card then you could do debugging. otherwise no way to do debugging.
