Yeap, PowerPC. > Is it possible to add some printk() calls in the probe function to > determine where it goes wrong? Well, I tried. First, if I have CONFIG_USB=m, CONFIG_USB_DEBUG=y, CONFIG_OHCI=m, CONFIG_SE401=m and CONFIG_VIDEODEV=y: (a) hotplug 20020401 doesn't go ahead and modprobe 'se401'. (b) modprobe'ing se401, the driver picks up the camera, and all seems well. Compiling everything in, only gets as far as: hub.c: port 1, portstatus 101, change 1, 12 Mb/s hub.c: port 1 connection change hub.c: port 1, portstatus 101, change 1, 12 Mb/s hub.c: port 1, portstatus 101, change 0, 12 Mb/s hub.c: port 1, portstatus 101, change 0, 12 Mb/s hub.c: port 1, portstatus 101, change 0, 12 Mb/s hub.c: port 1, portstatus 101, change 0, 12 Mb/s hub.c: port 1, portstatus 103, change 10, 12 Mb/s hub.c: USB new device connect on bus1/1, assigned device number 2 usb.c: kmalloc IF c3b97760, numif 1 usb.c: new device strings: Mfr=1, Product=2, SerialNumber=0 usb.c: USB device number 2 default language ID 0x409 Product: CABO II Oops: Exception in kernel mode, sig: 4 And the prink I inserted at the top of the function never gets called. -- Tom Rini (TR1265) http://gate.crashing.org/~trini/ _______________________________________________________________ Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ _______________________________________________ [EMAIL PROTECTED] To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-devel
