None of the built-in hubs supported this though, and this particular "feature" got me extra disappointed: No overcurrent protection And here I thought everything on a modern motherboard hade overcurrent protection. :/ Luckily both two hubs I had lying around supported power switching though (confirmed it using a optical mouse). Now for the fun part. Once I put an extra hub between the host and the IR device, it started working nicely on boot. So no power hack needed. :) Rgds -- -- Pierre Ossman Linux kernel, MMC maintainer http://www.kernel.org rdesktop, core developer http://www.rdesktop.org TigerVNC, core developer http://www.tigervnc.org WARNING: This correspondence is being monitored by the Swedish government.
