As mentioned earlier, it's been a few years since I worked on the c67x00, but are you sure you're using the correct interrupt number for it? Do you ever receive any interrupts from the device? PowerPC uses virtual interrupt numbers, so the '17' above doesn't to the hardware number. You can 'cat /proc/interrupts' to see what hardware number is used. I'm not sure how you exactly map between hardware and virtual irq numbers for platform devices. For open firmware devices you can use of_irq_to_resource(). PEIXOTO> Does the driver support bulk transfers and isochronous transfers? Bulk transfers should work for sure, and I think iso as well, but I'm not completely sure anymore. -- Bye, Peter Korsgaard -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
