usb_free_bus() is a Linux 2.4.x function (not in 2.6.x).
usb_connect() : same.
usb_new_device() and pci_find_class() in in 2.6.10.

What is the last kernel version that this worked on?

You would be better off asking for help with this on the
lin...@li...  mailing list.

Also, have you looked at http://www.linux-usb.org/usbtest/  ?
