Since udev-157 (+extras), when booting the system or restarting udev daemon, the usb dongle wich manages logitech keyboard and mouse has to be disconnected and reconnected to be functional. Issue dissappears if compiled wit 'extras' use flag unset. Traced udev git (installing custom ebuilds -derived from current 9999- which installed commits from 157 on) and found "ba854cf8c32a85e9415debdb8d2a7292ddb3c452"[1] being the offending commit. ------------ [1] http://git.kernel.org/?p=linux/hotplug/udev.git;a=commit;h=ba854cf8c32a85e9415debdb8d2a7292ddb3c452 Reproducible: Always Steps to Reproduce: 1. Set +extras for udev. 2. Install any version >157 3.
In the fora thread there are relevant logs.
Frankly, should be reported upstream. There's a post-160 git commit ("hid2hci: fix Logitech diNovo, MX5500 and other keyboards") that reverts a part of this change. See, if it's sufficient.
Here the issue is fixed with upstream git commit "a466c239a98045767c3aa7dfbf95306f36b9bf48". Sorry for the noise and thanks for your time and the info. Cheers
