Mutiple GSMopen USB modem setup
Hello! I have run GSMOpen on CentOS 5.7 defying the Wiki advisory. Questions: 1. What is the maximum number of USB modems tested? Can we get the numbers and the CPU used? 2. I'll be installing multiple modems each connected to a different mobile network. Is the /dev/ttyUSB assignments constant for every modem? Meaning it doesn't change if I plug it on different USB jacks.

I would invite you to go for the OS distros detailed in the wiki page. You'll probably encounter problems with different distros, and you're on your own to solve it.
1. What is the maximum number of USB modems tested? Can we get the numbers and the CPU used?
I've heard about 48 concurrent, and 64. Me personally have tested with 5. No CPU consumption. The critical part is the USB BUS. So use cascading and POWERED good usb 2.0 hubs
2. I'll be installing multiple modems each connected to a different mobile network. Is the /dev/ttyUSB assignments constant for every modem? Meaning it doesn't change if I plug it on different USB jacks.
it will change not only if you change USB port, but also randomly if you stay on the same USB port and reboot (and sometimes also without rebooting). That's a "feature" of Linux distros (a demented one, cannot understand why they choose this behavior). Soon or later I'll look into this, and come out with a solution (I've made some preliminary research and reasoning about in the past). If you have a commercial interest in that, and a real budget for it, contact me in private as consultant, or put a public bounty on it. -giovanni -- Sincerely, Giovanni Maruzzelli Cell : +39-347-2665618
Thanks for the feedback Giovanni. Re fixing the ttyUSB port assignment, I have searched a guy made a script to scan USB serial numbers using udev, then created symbolic links. Will try it out later. /Nandy On Thu, Dec 13, 2012 at 7:02 PM, Giovanni Maruzzelli <gmaruzz@gmail.com>wrote:

Hi Nandy, how it was? It works with that udev thing? Can you describe for me, so I can put it in the wiki? -giovanni On Sun, Dec 16, 2012 at 3:08 AM, Nandy Dagondon <nandy1925@gmail.com> wrote:

Hi Giovanni, I have not tested it yet. As mentioned by Dmitry, modem serial numbers are not accessible. Perhaps, mapping the serial port based on the USB port where they're connected would, at least, a workable solution somewhat as discussed in this post: http://stackoverflow.com/questions/4800099/how-to-identify-multiple-usb-seri...

it will change not only if you change USB port, but also randomly if you stay on the same USB port and reboot (and sometimes also without rebooting). That's a "feature" of Linux distros (a demented one, cannot understand why they choose this behavior).
Soon or later I'll look into this, and come out with a solution (I've made some preliminary research and reasoning about in the past).
If you have a commercial interest in that, and a real budget for it, contact me in private as consultant, or put a public bounty on it.

I tried, not so hard, but it does not work. :( At least on Debian Wheezy. Linux Udev system is changing too often, so I decided to use /dev/serial/by-path/* for persistence. 2012/12/19 Giovanni Maruzzelli <gmaruzz@celliax.org>
yep, seen that.
I was hoping for something tried and true :).

Here (http://wiki.e1550.mobi/doku.php?id=troubleshooting) you can find some useful info and udev rules file. Do not tried it yet, but it seems it can work. Maybe after slightly patching.

Nandy and Dimitry,
please let us know your findings.
Thanks for sharing!

Hi Giovanni,
I have not tested it yet. As mentioned by Dmitry, modem serial numbers are not accessible. Perhaps, mapping the serial port based on the USB port where they're connected would, at least, a workable solution somewhat as discussed in this post:

Hi! Huawei USB modems does not have accessible via USB protocol serial numbers. At least E1550, E153 and E171. Best wishes, Dmitry.

Thanks for the feedback Giovanni. Re fixing the ttyUSB port assignment, I have searched a guy made a script to scan USB serial numbers using udev, then created symbolic links. Will try it out later. /Nandy
