However, this setting was not present in 2.6.21-rc3, from which configuration I ran 'make oldconfig'. Make oldconfig does ask for this feature: USB device class-devices (DEPRECATED) (USB_DEVICE_CLASS) [N/y/?] (NEW) And I chose the default, breaking (my version of) lsusb, on Ubuntu Edgy Eft. I enabled USB_DEVICE_CLASS, and lsusb worked again. Thank you both for your quick answers! Please consider this patch which clarifies the need for USB_DEVICE_CLASS: --- ./drivers/usb/core/Kconfig~ 2007-05-27 11:22:22.000000000 +0200 +++ ./drivers/usb/core/Kconfig 2007-05-27 11:22:22.000000000 +0200 @@ -54,7 +54,8 @@ device of the interface and therefore easily accessible from the interface event. - This option provides backward compatibility if needed. + This option provides backward compatibility and is required on + many distributions to keep lsusb working. config USB_DYNAMIC_MINORS bool "Dynamic USB minor allocation (EXPERIMENTAL)" -- http://www.PowerDNS.com Open source, database driven DNS Software http://netherlabs.nl Open and Closed source services - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
