Ugh, I only have about half a dozen or so different types of USB devices (and even fewer of them are HID devices), so my experience isn't exactly a statistically valid sample. Having said that, out of that 6 or so devices, that particular keyboard is the only one causing crashes. However, note that it works (mostly) fine under 2.4 and even if they keyboard were total crap, it certainly shouldn't crash the kernel. --david
