#2 licut_probe.cpp endpoint class_dirname not found on recent Linux kernel (or my particular distro)

[Geremia]

I don't know much about Linux USB interfacing, but I'm having trouble getting the endpoint open. Line 62 of licut_probe.cpp is not correct for recent Linux kernels (or at least not for my distro, Slackware):

sprintf( class_dirname, "/sys/class/usb_endpoint/usbdev%u.%u_ep%02x/device", bus, device, test_ep );

I don't have a /sys/class/usb_endpoint/ directory. What should I use instead?

Also, I've had to apply this patch to get the USB ID / bus numbers correct:
