i have proceeded to do what you said above and my set up appears different.
my softmod was done using shadowsonic 2's guide aprox 16mths ago.
on my sd card the apps folder does'nt have a usb gx folder only the following sub folders.
any title deleter mod.
wad manager v 1.5.
hermes cios installer.
trucha bug restorer v1.12.
i have another folder on the sd titled config.inside this there is 3 .cfg files.(1)gxgamefavourites.cfg. (2)gxgamesettings.cfg. and (3)gxglobalconfig.cfg.
also on the sd root there is a folder titled wad,and inside it contains the usbloader gxr938 wad.
there is nothing else on the sd relating to usb gx.
i havent changed anything yet till i clarify what im about to do is correct.
do i delete the entire folder titled config?.
do i then replace the r938 wad with the new 2.2 version in the wad folder?.
and should i update the wad manager from 1.5 to 1.7 first?.
again thanks for the help.
