Hi, (ever so awesome and we are all super unworthy) - Kernel peoples! I have found this dmesg error message which appears to be written in the xHCI host controller. (or maybe it originated in EHCI, i don't know.) None the less the issue is: "Not enough host controller resources for new device state" I noticed from a few git repos. that this is in the xhci.c file that the code has below it: FIXME: can we allocate more resources for the HC? Anyway, the git has Sarah Sharp on it. Sarah, are you on this mailing list? So I would really like to know how to get some more of these pretty resources... if its possible at all? I am running Kernal 3.11.0-12-generic, but am happy to change if I have to. A very brief summary is that I'm trying to connect 16 CDC usb devices to one machine. ( I do engineering for artists and I build these: http://vimeo.com/60491636 ) I have a full description of my investigations on serverfault.com http://serverfault.com/questions/583528/not-enough-host-controller-resources-for-new-device-state I'm really at a loss here on where to go next with this and I have a major international airport coming up to Stockholm next week to see some of my work. best regards.
