Hello,

 

I have juste generated a i.MX233 Linux image with LTIB (Min profile + usbtools package).

When typing lsusb I get no device whereas a USB device is connected.

 

I tried to see what happened with strace but now way to see something clear:

 

open("/sys/bus/usb", O_RDONLY|O_NONBLOCK|O_LARGEFILE|O_DIRECTORY|0x80000) = 3

getdents(3, /* 1 entries */, 32768)     = 152

getdents(3, /* 0 entries */, 32768)     = 0

close(3)                                = 0

io_submit(0x1, 0x946c0, 0x8 <unfinished ... exit status 1>

Process 2125 detached

 

Never got such a weird behaviour with the i.MX25 3-stack.

 

I suspect an issue in the USB directory (/sys/bus, /proc/bus, /dev/bus ?).

 

Any idea ?
