From ec2ff62746325b0d889bc632c9b833aa92cf3eda Mon Sep 17 00:00:00 2001 From: Valentina Manea Date: Tue, 7 Jan 2014 21:05:56 +0200 Subject: [PATCH] staging: usbip: userspace: add support for viewing imported devices As of Matt Mooney's major refactoring in 2011, usbip port option was left out. Add support for this option in a manner similar to the old implementation.
