VirtualBox includes a version of rdesktop with added support for USB redirection, usable with their products. Gentoo ebuild of virtualbox-bin does not seem to include this version of the client, so I propose adding USE=rdpusb to the official one. Ebuild using a cleaned-up diff of the VirtualBox version to upstream is attached. Reproducible: Always Steps to Reproduce:
Created attachment 216295 [details] Ebuild with a rdpusb patch included
Created attachment 216296 [details] Diff to the in-tree ebuild
Sorry for the delay, this is now in 1.6.0-r4 ebuild. Thanks for report and patch!
(In reply to comment #3) Bernard, have you actually pushed the patch to the mirrors? :) The updated ebuild is there, but the patch is currently missing even from distfiles.gentoo.org.
Indeed, sorry about that! It should get to mirrors on next sync
