Your log shows nothing wrong except that the Cruzer Micro doesn't send any data back in response to READ commands. No explanation for why not. You say the same device works perfectly if you plug it in after the system has booted. Can you capture the log messages (with all the debugging settings turned on as before) showing this? Perhaps comparing the two will show up some difference. Alan Stern ------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
