Ricoh Drivers for Ubuntu 10.10

October 12, 2010 Leave a comment

If you try to compile r5u870 driver for Ricoh webcams under Ubuntu 10.10 you’ll fail due to a recent renaming of some functions in the linux kernel.

In particular:

usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free()  is renamed to usb_free_coherent()

For more information:

To avoid this problem, make this substitution in the usbcam_util.c file that can be found here: ttp://
