Hi all. * I tested on XO-1.75 with os14; the frame appeared fine (booting-up with the USB-flash drive, and USB-modem inserted) !!!!!!!!!!!!!!!!!!! * Pulling off my hair, I re-tested on XO-1.75 with os11 (booting-up with the USB-flash drive, and USB-modem inserted) ; thankfully, the frame-icon did not appear (as before). * I then tested on XO-1.75 with the os12 (booting up with the USB-flash drive, and USB-modem inserted); the frame-icon appeared FINE here too. I compared the packages-difference between os11 and os12; os12 has an updated version of usb_modeswitch and usb_modeswitch_data. Also, in os12, there is no more the error <pre>usb_modeswitch_dispatcher: *** glibc detected *** usb_modeswitch_dispatcher: double free or corruption (!prev): 0x00081fe0 ***</pre>that was happening in os11 (in the culprit case, that is). So, bad news : Things are happening without us knowing the root-cause :-\ good news : Seems like <a href="http://dev.laptop.org/ticket/12340">http://dev.laptop.org/ticket/12340</a> can be closed :D Thanks everyone for the help (especially James). <div class="gmail_quote"> On Sat, Nov 24, 2012 at 10:31 AM, RJV <<a href="mailto:jv.ravichandran@gmail.com" target="_blank">jv.ravichandran@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Thanks, James/Tony.
