Mageia is not detecting my USB modem (POTS)

I have always kept a dial-in connection available, as a back-up for those times when my broadband ISP (Clearwire) fails.

Older versions of Mandriva supported this, but the latest updated Mageia shows my US Robotics USR5637 modem under "Other" in the hardware list and does not seem to provide a setup wizard. I clicked the check-box to "auto-detect modems," but this had no noticable effect, even after a restart of the computer (when I used Windows hardware manager to make certain this isn't a hardware issue).

Is there a way to get Mageia to detect and use this USB modem?

Can you please show the output from
Code: Select all
lsusb

You may need to install usbutils to use this command.

Also, some more informations. You switched directly from some older Mandriva version to Mageia 3?
Where was the modem listed before (which category) and which program was used to set it up?

Pardon the delay. here's the resulf from lsusb:

The last device is the USR5637 modem. Mandriva detects it, but using the Gnome GUI hardware wizard, it is not identified as a modem. It is listed as "Unknown/Others" along with the PL2303 usb-serial adapter.
Unfortunately for me, I have been adopting new versions of Mandrake, Mandriva, and Mageia as they appeared, without keeping good documentation. Thus, I cannot tell you which version last supported this modem.

I hadn't spent any time looking deeper into this question since, but if anyone is interested, Mageia 4 doesn't seem to know what to do with that USR5637 USB modem either.
Even faithful old Kppp just tells me the modem is "busy" no matter which of its listed ports I use to query it.

There is no cdc_adm driver in Mageia 4 or in Mageia 3. Similarly, an internet search for that driver comes up blank. There is a cdc_acm which is a USB modem driver, and a cdc-wdm which is intended for USB wireless devices (presumably modems). Was cdc_adm a typo?

Edit: the PL2303 is well supported.

Yep, sorry - was referring to cdc_acm. Well spotted, thanks 8-)

Hence the commands should be

Code: Select all
lsmod | grep cdc
journalctl -ab | grep -e cdc -e 2023

Well, I've wandered back into this place at last, and I see there was a request for some information. Once again, sorry about the delay.
Let's see... how to paste as code to retain formatting...
Code: Select all
[root@localhost username]# lsmod | grep cdc
cdc_acm                32881  0
usbcore               230079  8 usblp,usb_storage,ohci_hcd,ohci_pci,ehci_hcd,ehci_pci,usbhid,cdc_acm
[root@localhost username]# journalctl -ab | grep -e cdc -e 2023
Jan 25 09:09:42 localhost kernel: Built 1 zonelists in Zone order, mobility grouping on.  Total pages: 1932023
Jan 25 10:05:48 localhost kernel: cdc_acm 5-3:2.0: ttyACM0: USB ACM device

Jan 25 10:05:48 localhost kernel: cdc_acm: USB Abstract Control Model driver for USB modems and ISDN adapters
[root@localhost username]#

So, trying to make sense of that, the USB modem should be on ttyACM0..?
I really need to get back to using the text console instead of the GUI. I've forgotton most of what little I ever knew.

Yep, looks good so far.
