From 9013d8fc0ad91dc369f5b8ea708b9b068aa5d434 Mon Sep 17 00:00:00 2001 From: Khalid Masum Date: Thu, 25 Aug 2022 02:31:07 +0600 Subject: usb: host: Initiate urb ep with udev ep0 Currently we look up for endpoint in a table and initate urb endpoint with it. This is unnecessary because the lookup will always result in endpoint 0.
