[TRANSIENT ISSUE] 3G-Modem not being recognised
Hi all. I have been facing transient issues in getting the 3G-Modem recognised (via the appearence of the corresponding icon in the bottom-tray). There really is no fixed pattern; sometimes the icon appears when the modem is inserted; sometimes not. Same is the case when the XO is rebooted, while the modem is inserted. Upon booting, sometimes the icon appears; sometimes not. I don't remember such issues in 12.1.0; there, the icon appeared whenever it ought to. Is someone else too facing such transient issues; or am I the only one hit?

Re: [TRANSIENT ISSUE] 3G-Modem not being recognised
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.

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.

Re: [TRANSIENT ISSUE] 3G-Modem not being recognised
Yes, Ajay, it does happen the way you describe so what I do is make sure that I have the device plugged in before starting the XO otherwise, you need to restart the XO for it to recognize the device or you need to switch desktop and upon returning back to Sugar, the device would be recognized.

Every device is different, it is impossible to predict the outcome, unless you are able to identify the exact device and find someone who has used it.

Re: XO 1.5 and 3G connectivity
But you didn't identify the device. There are hundreds of different 3G USB devices, with different circuits, USB ID, firmware, and configuration settings. http://quozl.linux.org.au/bp3-usb/ was my last foray into this field, and it has grown more complex since, with more vendors and networks. You would need to identify the device to be able to get use out of anybody else's experience. Suggested identification methods: - manufacturer, model, - USB ID shown by lsusb or kernel messages, - network configuration supplier.

Please provide me about 5-6 hours (I have 56KBPS download-speed connection). Good, additional justification for finding a way to make our build files much smaller. ;-} It takes me a while too.
