It may help adding the -I switch to the cmd line when using that obsolete version of usb_modeswitch.

Thank you for your quick response , the problem esque change just stands right after (OK , driver "usb -storage" detached ) but on another computer with the same software works correctly .
I do not think that is the obsoleted version.

I think the problem is the USB 3.0 ports

I do not think that is the obsoleted version.

The current version of usb_modeswitch uses the modern version of 'libusb' which likely will work much better with USB 3.0 ports.

You can easily compile the current version yourself to test it yourself.

solved with minicom, change AT^U2DIAG=0.
Thanks
