Let me guess: You have "hid.o" or "mousedev.o" loaded?
As soon as they are loaded they grab the device. Later on, when you use "lsusb", it also tries to grab the device to do an usb_control_msg(), which fails. Someone proposed an ioctl() some time ago to force a kernel-module to release an interface, but I never saw it implemented. A workaround is to unload everything "hid" specific and than do "lsusb". Which is hard if you only have an USB keyboard ...
