it works now! And I'm a little ashamed of why it didn't before:
svn diff -r HEAD Index: Makefile =================================================================== --- Makefile (Revision 89) +++ Makefile (Arbeitskopie) @@ -1,6 +1,6 @@ KERNEL_VERSION := `uname -r` KERNEL_DIR := /lib/modules/$(KERNEL_VERSION)/build -INSTALL_MOD_DIR := usb/media +INSTALL_MOD_DIR := kernel/ubuntu/media/usbvideo PWD := $(shell pwd) adding the trace messages showed me, that I wasn't using the downloaded module at all, but the module provided by ubuntu. If you don't mind I'll drop a bugreport at https://launchpad.net/ telling em that the uvcvideo module they provide is outdated.
