I also tried using a different visualization package (was using vmware but also tried virtualbox) and different linux distros but no luck so far.</SPAN><BR /><BR /><SPAN>I also tried to downgrade the version of JLink software I'm using but after trying at least 5 older versions without being able to get it working I just stopped trying. One thing I noticed is that when issuing the command showemulist I got the following:</SPAN><BR /><TABLE border="1"><TBODY><TR><TD bgcolor="#cacaca"> <PRE> <I>J-Link[0]: Connection: USB, Serial number: 0, ProductName: J-Link</I> </PRE> </TD></TR></TBODY></TABLE><BR /><SPAN>As you can see the adapter is listed but JLinkExe fails to read the serial number, I can access adapter's info using "lsusb -v -d 1366:0101" and as you can see in following output it does retrieves the correct serial number</SPAN><BR /><TABLE border="1"><TBODY><TR><TD bgcolor="#cacaca"> <PRE> sudo lsusb -v -d 1366:0101 Bus 001 Device 003: ID 1366:0101 SEGGER J-Link ARM Device Descriptor: &nbsp;
