please rebuild your kernel with CONFIG_USB_DEBUG=y.

These messages are all consistent with the modem being disconnected (this can occur for many reasons, such as electrical problems, and not just unplugging it). I see from the rest of the log that it doesn't always happen at the same point, eg URB147 failed above, but not below. > NET: Unregistered protocol family 20 > speedtch: Unknown symbol usbatm_usb_disconnect > speedtch: Unknown symbol usbatm_usb_probe I don't know what these unknown symbols are about. I can only imagine that you are loading modules compiled for a different kernel version, or something of that kind. > NET: Unregistered protocol family 8 > speedtch: Unknown symbol usbatm_usb_disconnect > speedtch: Unknown symbol usbatm_usb_probe > speedtch: Unknown symbol usbatm_usb_disconnect > speedtch: Unknown symbol usbatm_usb_probe > speedtch: Unknown symbol usbatm_usb_disconnect > speedtch: Unknown symbol usbatm_usb_probe > speedtch: Unknown symbol usbatm_usb_disconnect > speedtch: Unknown symbol usbatm_usb_probe > NET: Registered protocol family 8 > NET: Registered protocol family 20 > usbcore: registered new interface driver speedtch > usbcore: deregistering interface driver speedtch > ATM dev 0: usbatm_complete: urb 0xd6d04840 failed (-2)! > ATM dev 0: usbatm_complete: urb 0xd6d048c0 failed (-2)! > ATM dev 0: usbatm_complete: urb 0xd6d04940 failed (-2)! > ATM dev 0: usbatm_complete: urb 0xd6d049c0 failed (-2)! > ... whole sequence repeats forever, with the messages in no > particular order. > > So my question is.... what has happened to the kernel since 2.6.17.8? Lots changed in the kernel and the USB layer. Nothing changed in the speedtouch driver between 2.6.17 and 2.6.18. There were some changes for 2.6.19. > Why does the usbcore register and then immediately deregister the > speedtch module? Does URB147 fail because the module is deregistered, > or vice versa? And why are usbatm_usb_disconnect and usbatm_usb_probe > unknown symbols? Are you using enable_isoc=1? Do you also have the userspace driver (it could be forceably disconnecting the kernel module). Did you build and install your kernel + modules correctly? Ciao, Duncan. Liste de diffusion modem ALCATEL SpeedTouch USB Pour se désinscrire : mailto:[EMAIL PROTECTED]
