I don't know what iTLS Enso is, but if it's the enso fork, I'd be careful. the one I'm thinking of -- many have bricked from. post the content of your config.txt here (what firmware are you on?).
It's not the Enso fork it's a plugin to bring TLS 1.2 support for Enso, anyways I've removed it and USBMC (which apparently isn't needed to have USB as ux0?).
Anyways here's a copy of my config.txt placed in ur0:/ai/
# This file is used as an alternative if ux0:tai/config.txt is not found.
# For users plugins, you must refresh taiHEN from HENkaku Settings for
# changes to take place.
# For kernel plugins, you must reboot for changes to take place.

Everything else is ur0:tai/ I have no idea what's going on, I've never had this issue on my Vita 1000. None of the plugins I add are getting loaded on boot. I don't know if it's a bad Enso installation or boot_config is incorrect (it shouldn't be I haven't touched it), but I could really use some help. I used autoplugin to reset my config.txt and nothing.
