help debugging usb

Mon Dec 24, 2018 10:31 pm

hello,
i've a strange problem i can't understand so i need some help :)

i have a playstation3 eye
a raspi 3a+
when i first boot up, it works flawlessly
when i reboot, it stop working. i mean, it's visible in a lsusb, but with an arecord command, it doesn't record and hangs the proram.

the strange thing? if i connect the same cam to a raspi 2B, updated the same, it works even after a reboot!

i also tried with 2 different power cables but with no luck..
and i tried swapping sd cards. no luck again.
what am i missing of the 3a+?

thanks

Massi

ok guys, it seems also harder now..

I took my 3B+
4.14.71. Working on startup, Working on reboot.
Updated to 4.14.79. Working on startup. Working on reboot.

So i took the very same sd and put it in the 3a+
Working on startup. Not working on reboot (!!!!!)
how the hell can it be?

May i ask if there is any difference in usb management between 3a+ and 3b+? is it something i can try to modify?
thanks :(
