Although this is clearly a possibility which occurred to me, it may not be quite that simple. Also, there are a multitude of modules, any number of which may interact in this case. I can certainly test it by rebuilding the kernel if you have any idea at all which module(s) could be responsible. However, I was hoping that this problem might have been brought up before, which might have provided a clue, but I found no such luck so far. > BTW according to these Gentoo Docs lsusb uses /proc/bus/usb not > /dev/bus/usb Yes, thanks, I should have been clearer. Neither '/proc/bus/usb' nor '/dev/bus/usb' exists after building this kernel. The /dev/bus reference was how it used to be handled by devfs if I am not mistaken, but I am not a programmer.
