I can confirm this approach works.  I haven't given it
exhaustive tests, but in the 6-12 MB/s range "it works
for me" just the way it used to under debian sarge.

To try it out yourself:
  apply the fusb_linux.cc patch from my previous e-mail
  grab linux.h from libusb_0.1.10a
     (debian users can just "apt-get source libusb")
     and put it in usrp/host/lib/libusb_linux.h
  disable linux/usbdevice_fs.h checking in config/usrp_fusb_tech.m4
     (patch appended)
  bootstrap, configure, make install, test

It is normally considered proper to avoid direct reference to
kernel header files.  The practical problem is tracking changes
to the interface, but I suppose the libusb folk can do that for us.
