Hello, I would like to forward the patch that is being used for years in Fedora and Gentoo to fix connectivity issues of JMicron devices with UAS when they got into idle state: https://bugzilla.redhat.com/show_bug.cgi?id=1260207 https://bugs.gentoo.org/640082 The problem is still valid with current kernels, then, I guess the patch wasn't forwarded here or got forgotten for some reason. This patch works fine for current kernel 4.13.11 too Thanks a lot
