Recently it has stopped behaving properly and begun reporting errors and at times not communicating with the phone at all. The phone is connected via a USB2 port directly connected to the mother board (this has been previously very reliable). I have the Cyanogen-mod/Android OS on the phone (having got rid of the Samsung/Android OS 9 months ago). I have another XUbuntu machine I only run Apache and Python3 on to provide a community website and a 24/7 weather site. This other machine picks up the phone OK and allows the usual file transfers etc. For convenience I would much prefer mount the Galaxy S on the Desktop and access the USB storage that way. I have tried to find a Linux utility program that might cast some light on the problem but failed to do so. All my other USB devices appear to be working OK (Ext USB1Gb, Canon Scanner, Flash Card reader, Canon iP4200 printer, and of course, mouse and keyboard), and the usual typical USB memory sticks are ok. Here the command line, 'lsusb' reveals the connection is found (Nexus S?)- <tt>rob@DesktopUbuntu:~$ lsusb</tt><tt> </tt><tt>Bus 002 Device 003: ID 04fc:0c25 Sunplus Technology Co., Ltd SATALink SPIF225A</tt><tt> </tt><tt>Bus 002 Device 002: ID 04a9:10a2 Canon, Inc. iP4200</tt><tt> </tt><tt>Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub</tt><tt> </tt><tt>Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub</tt><tt> </tt><tt>Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub</tt><tt> </tt><tt>Bus 001 Device 055: ID 18d1:4e21 Google Inc.

Phone's Storage: Internal Storage: 1.26GB & 546MB available USB Storage: 13.4GB & 10.07GB available So neither appear close to their limit? The internal USB memory size is usually reported as16 GB, but now the desktop reports it as 14GB, and then fails to mount the volume. <img shrinktofit="true" alt="" src="cid:part1.04010206.09000408@bigpond.com" height="100" width="660"> I am guessing the problem lies with my XUbuntu desktop machine, but I need help to even begin to tackle it. Any ideas? Any help at all towards solving this would be greatly appreciated. -- Rob Ward </body> </html>
