Well, freescale patch should work :-) (they says yes). I have opened a
support request for this topic... but maybe some people is on vacations
there...

No, i have some program in mx21 that should be listening in
/dev/ttygserial and from Desktop computer I will "talk" to /dev/ttyUSB0
(to send some commands to mx21 via serial port). This is working using
Net2280 card without problems...

Now I haven't access to MX21 (I am not in the university). The modules
wasn't related to USB, and then I tried to load (Freescale told us 3
weeks ago, but I was on holidays...):
usbdcore.o
mx2_bi.o
And no signal in lspci from Desktop.
Then I was trying usbd_drv.o, usbdrv.o, usb-mx2otg.o, mx2usbd.o without
success (I was loading and unloading to see if something happends...)
I think that only with USB device controller driver should appear on
Desktop lspci (because I am saying a VendorID and ProductID in Kernel
configuration)
I tried everything inside the Kernel and same results...
Thank you for your attention,
