Mobidata Edge Modem

Post by chuina » 2009/12/16 17:57:02

Helo,

I'm using Mobidata Usb Modem in other Linux (Ubuntu9.10).
its model is: MBD-100EU

is it compatible in CentOS5.4.
i can't run the "lsusb" because i'm still in the Live CD mood!!!
But the Hardware Service detect it as Mobidata modem.

"dmesg | grep usb" shows the detection but dont attached any of the /dev
also i can't run the "modprobe" command due to Live CD mood!!!

Where (in the web) may i find the supported USB list for CentOS5.4 .

Thanks very much.

You can run /sbin/lsusb from the LiveCD as I explained in your [url=https://www.centos.org/modules/newbb/viewtopic.php?topic_id=23822&forum=39&post_id=93760#forumpost93760]other thread[/url]. The critical information is the pair of 4 digit hex numbers, the [i]Vendor:Device ID pairing[/i]. This will determine if a driver is available. For an example see

It detects the modem by /sbin/lsusb something like :

centos@desktop:~$ lsusb
Bus 001 Device 001: ID
Bus 005 Device 001: ID
Bus 002 Device 002: ID 10ce:ea6a Silicon Labs MobiData EDGE USB Modem
Bus 002 Device 001: ID
Bus 003 Device 001: ID
Bus 004 Device 001: ID

But do attach in /dev/tty.....

and Is there anything like gnome-ppp in CentOS 5.4 ?

thanks .

Unfortunately there seems to be no driver available for that hardware.[code]grep -i 10ce /lib/modules/*/modules.alias | grep -i ea6a[/code]returns nothing. You either need to find a driver, acquire compatible hardware, or use a different approach to networking.

Your other thread did mention a Windows machine on the network. Is setting up connection sharing or acquiring a cheap router out of the question?

Thanks for keep helping me.

I can install this Modem's (and others) driver by wine.
But wine didn't detect the Modem auto.

If I'm willing to setup CentOS/Linux as server then why should i get help from a Windows Platform ?!?
It is our common local question.
Many people wished to switch in Linux. But stopped due depends on Windows !
As if CentOS is not fulfilled as it should be as a open source software/os.

(But i know Linux based servers are excellent in performance, but for that CentOS have to install first.
i saw in the LiveCD ,that there are some softwares like Graphics,Office,and other non-Networking related
softwares. i hope CentOS authority should exchange them with installation related materials. Cause, we
choose Linux Based OSs for Networking,Browsing Basically)

Thanks for your valuable time.

helo, me again,

I've found that my lonely modem is supported in Fedora :[url=https://fedorahosted.org/hwdata/browser/usb.ids?rev=9fe002b2873ddc29b8c01768f9b93095012c3491]here[/url] in line 5131,5132

Since, the softs of fc6 are widely compatible in CentOS (i'm using total fc6 gnome in CentOS)
is it possible to add/import fedora's hardware driver in CentOS 5.4 ? if yes then how ?

thnx

Hmmm - looks like it should be possible. Perhaps [b]toracat[/b] or another of our more kernel-module-literate contributors can comment. Might be in the CentOSplus kernel.

Aside: Is there a way to know the list of centosplus kernel modules without installing it, or magic with rpm/cpio/etc.? Perhaps my search-foo is off today, (never mind dredging it up out of wetware long-term storage) but I'm coming up empty.

I've had my tail gently tweaked by [b]toracat[/b] to suggest that I should comment.

Using some of my other search techniques, I see that a driver for a device with the [b]10ce:ea6a[/b] fingerprint was first present in the mainline 2.6.30 kernel . . .

The driver in question is [i]cp210x.c[/i]. It was at [i]v0.08[/i] in the mainline 2.6.30 kernel and went to its current version, [i]v0.09[/i] in the mainline 2.6.31 kernel.

[b]Phil[/b], I can assure you that that driver will not be in the [i]CentOS-Plus[/i] kernel. Any chance you would be able to sniff out the first [i]Fedora[/i] kernel which incorporates the [i]cp210x.c[/i] driver, please? And then point me to the URL to its source?

Depending upon many variables, it [i]may[/i] be possible to back-port it to the [i]EL5 2.6.18-x.y.z.el5[/i] kernel series as a kmod package . . .

Ah - serial tweaking. :-D

Good to have the right man on the job.

I see that I mis-interpreted post#6 as evidence that it was in FC6 and thus likely in the CentOS kernel sources.

Presumably that is to be left as an exercise for the OP. How about it [b]chuina[/b]?

I'm sure that would be much appreciated. Thanks.
