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 usb_modeswitch_dispatcher: *** glibc detected *** usb_modeswitch_dispatcher: double free or corruption (!prev): 0x00081fe0 *** 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 http://dev.laptop.org/ticket/12340 can be closed :D Thanks everyone for the help (especially James).

In the second test, memory stick and modem plugged in before boot, I got to the connected display in the frame but the upload and download kB counters never updated past 0 even though I was browsing, the connected time did update ok. Interesting, thanks. Updated SL #4255. I've never seen data counters in 13.1.0 builds. I did not try without the memory stick.

In the previous thread this was discussed in (See Patch: Mobile dongles) the proposal was that inhibit would be triggered by the presence of module 'usb_wwan'. Jerry submitted patches that did that. Paul was wondering if there was a better way than looking for a module loaded. Powerd already has a mechanism where it disables suspend while an association is in process and Paul was wondering if you could leverage the existing infrastructure for this. The thread dies after that. So I think anyone wanting this to get integrated as a stock feature should investigate if you can use a NM hook to send the DBUS message to powerd to inhibit. -- Richard A.

Re: [Sugar-devel] [TRANSIENT ISSUE] 3G-Modem not being recognised
Thanks Ajay. Can you confirm this is on XO-1.75 with 13.1.0 os11? I think you mentioned XO-1.75 and 13.1.0 in a previous reply, but you might have changed the configuration since then. At step c, where the modem is not detected, I take it you mean that the Sugar frame icon does not appear. I know you said your nm_test.py script does not list the device. I wanted to test your nm_test.py. It seems reliable. In the same test, I was unable to reproduce your problem. My test is below. I suggest in your case obtaining kernel dmesg output for two scenarios: - the modem is inserted after Sugar has started, - the modem is inserted before power on. So that the kernel response to the USB device can be checked. -- I tested with 13.1.0 os12 on XO-4, and 12.1.0 os21 on XO-1.75 with a Huawei E173 bound to service vendor Optus in Australia. The modem was inserted in the socket and the laptop switched on. I waited for Sugar to be available. The modem does appear in the frame. I used My Settings to configure APN, then selected Connect using the frame icon. The connection completes and Browse can be used, but the frame icon does not change from saying Connecting (SL #4255). At this point, and before connecting, your nm_test.py script reports device 0 with type 2, and device 1 with type 8. At Terminal prompt the command nmcli dev properly lists /dev/ttyUBS0 as type gsm state connected. nmcli con properly lists the connection. nmcli con down uuid uuid properly terminates the connection, and the frame icon properly reports status of Disconnected. When I remove the modem from the socket, your nm_test.py script properly reports removed device 1 type 8, and when re-run does not report device 1 any longer. (Unrelated, why can't I copy a URL from the Browse activity location bar? I had gone to lists.laptop.org, to devel@ archives, to grab your nm_test.py attachment.)

Re: Re: [Sugar-devel] [TRANSIENT ISSUE] 3G-Modem not being recognised
Ajay You do not say which OS you are using or whether its Sugar or Gnome desktop. For most of 13.1.0 the modem dongle has not been appearing in the Sugar frame. It was fixed at OS11 I think but I have not tested it a lot to see if its always there in the frame. Tony I have heard from other people who have faced issues that may be similar at root. I suggest that you deepen your investigation to determine the reaction of the kernel, and the ModemManager process, to the insertion of the device. Compare the reactions between working and non-working scenarios. On Tue, Nov 20, 2012 at 02:03:49PM +0530, Ajay Garg wrote: Hi all.
