I am modifying some dated code (from year 2011; see here) that accesses a USB endpoint in the path:


where "BUS", "DEVICE", and "ENDPOINT" vary.

However, my Linux setup (Slackware 14.2; kernel 4.4.14) doesn't have paths of this form.

How do I access USB endpoints with recent Linux kernels?


They are under /sys/bus/usb.

For example,

ls /sys/bus/usb/devices/1-0\:1.0/ep_81/

bEndpointAddress  bLength       direction  power  uevent
bInterval         bmAttributes  interval   type   wMaxPacketSize
