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 ?
