Looking at ethtool GDRVINFO support in the USB network drivers,
some in 2.4 use usb_make_path() for their bus_info field, and some
use usb<busnum>:<devicenum>. Everything in 2.5 uses usb_make_path().

In 2.5, identifying devices with usb_make_path() is fairly simple;
it's all exported via sysfs. Is there a similar function in 2.4 to,
given a usb device, determine its usb_make_path() ID without
walking the entire USB and PCI trees?
