usbfs!!!
Changing USBDEVFS_DEVICES_NEW to /sys/kernel/debug/usb/devices allows
javax-usb-ri-linux to work for me. Hooray!
Also, thanks for the suggestions ...
FYI,

I found that in our deployment of the 3.5 kernel, we mount the debugfs under
/sys/kernel/debug, which has the devices file under usb/devices. So, I might
just be able to change
#define USBDEVFS_DEVICES_NEW "/sys/kernel/debug/usb/devices"
and it may "just work".
Gonna give that a try - will report back to the list with my findings.
I don't think assuming debugfs being mounted under /sys/kernel/debug is a good
assumption for the javax-usb-ri-linux project, but it may save my bacon.
(Arguably it is no worse than assuming other paths that it has hardcoded in the
past. And then just document that debugfs needs to be mounted there. Long
term, udev is probably the way to go ... (?) )
FWIW,

Thanks for that link! Unfortunately, they require java 6 and I am stuck on
Java 1.4 for other reasons ...

If you need another option then you may want to check out usb4java
(http://kayahr.github.io/usb4java/). It is a pretty young project implementing
javax.usb and using libusb 1.0 as backend.
