I have the same problem on several machines since debian sarge and also on every ubuntu-version i used. Sometimes lsusb works with no problem and then on the same machine it hangs without any output and I can only kill it from a other terminal via killall lsusb, after reboot of the machine everything works again. I found any log message until now.
