Hello,
I am moving my thread from the newbie forum
http://www.linuxquestions.org/questi...to-4175465972/ to here.
I have an embedded system.
Kernel 3.8.13.
I am booting with a specific kernel reduced to the minimum (drivers selected with "make menuconfig" and integrated in 1 kernel, not in diverse modules etc. etc.).
The last dmesg output is:
Code:

Now I am searching about a solution to make it working:
- libusb not working. Why?
- a working libusb is necessary for a working usb_modeswitch?
- it could be exist conflicts with usb-drivers (ohci, hso..) and modules should be unloaded / loaded as per link here
http://nslu2.10980.n7.nabble.com/Rep...n-td14588.html ?
Any advice / idea how to make progress is welcome.
