That may indicate the PREVENT-ALLOW MEDIUM REMOVAL command isn't the problem. I don't know about FreeBSD; does it have any way for you to monitor the data sent over the USB bus? With Windows, you can use the USB Snoop program (from sourceforge) to monitor the communication with the device. Comparing it to what Linux sends might indicate where the problem is. > By the way I looked into FreeBSD kernel sources and didn't find there > anything specific to my USB flash.

With that patch, this command wouldn't be here. Alan Stern ------------------------------------------------------------------------- Using Tomcat but need to do more?
