1680	/proc/bus/usb is obsolete	alexander@…	bdubbs@…	"While the instructions at the libusb page still work with linux-2.6.14, they
describe the obsolete setup. The /proc/bus/usb mount should go away, and libusb
should be patched to take advantage of real raw usb device nodes. Use this raw
message as a patch for libusb:

The udev rule that is equivalent to the current setup WRT permissions is:

SUBSYSTEM==""usb_device"", PROGRAM=""/bin/sh -c 'X=%k X=$${X#usbdev} B=$${X%%%%.*}
D=$${X#*.}; echo bus/usb/$$B/$$D'"", SYMLINK+=""%c"", GROUP=""usb""

(that is one long line)

Fine-tunuing of permissions is possible by creating extra rules, matching on
something like this:

SUBSYSTEM==""usb_device"", SYSFS{idVendor}==""05d8"", SYSFS{idProduct}==""4002"",
