could not start usb acc driver error

Hello,

I found my psp again after years of not using it! anyways i want to run mapthis again, i have used it successfully in the past but now it just won't work!!

I get the "could not start usb acc driver error"

I have downloaded and tried chilly willys key keycleaner.

MOBO is ta-082/86
Firmware 3.90 m33-3
I went into registry, made sure 1.50 kernel is enabled
PRX files im using 2.71 usbacc.prx and 3.03 usbgps.prx (but i doubt those would cause this error)


Any ideas?

I could have sworn i have to do something with toggle USB (flash 0) or flash 1 in registry


thanks

I am almost certain is has something to do with the Flash 0 and Flash 1 files in my Registry...im having some troubles trying to find the correct files to put in there...anyone know?

thanks

UPDATE

I just downgraded to 3.52 m33 and it works great!

re-edit

same error message after it has been working fine for the day!!

What in the HELL could be causing this? i am seriously DONE i literally downgraded to 1.50 and up to 3.52 m33 JUST for mapthis and now i get the same error after 1 day of use...

I SWEAR THIS IS MY LAST UPDATE! haha

to get it to work again after it worked for only a day until that usb acc driver error came back...

FIX..

go into Recovery, advanced, reformat your flash 1 and reset settings..worked like a charm for me.


Hope this helps anyone else! this drove my crazy for a couple days
