I don't know of any opensource windows usb drivers, sorry. You should contact a Windows mailing list, or even better, Microsoft, as this seems to be a bug in their code, which is not anything we (i.e. Linux developers), have any control over. The fact that you can crash a box by plugging in a "bad" device, has all sorts of security issues... good luck, greg k-h -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
