Ah: I forgot to say something... (sorry... should have written everything on the same e-mail)
We've been analyzing the usb module files, especifically the file driver/usb/core/hub.c . Looking at the function usb_reset_device (the last one on the file), I saw that there is a variable called udev->state, and one of its state is "USB_STATE_NOTATTACHED". I (still) don't understand how udev, or usb, or anything works, but I've been thinking: Is there a way to change the usb state to usb_state_notattached, and then change it back to "attached"? To execute all the functions that are executed when the device gets attached... Me and the guys who work with me are going to investigate it, but anything you guys could say would be very helpfull. Desperate solutions =( Thanks a lot! Paulo. >> And what happened when you tested? > The same result as we always had...
