I have an annoying problem with my umts-pcmcia modem (Huawei E620). Networkmanager does not dial from it. BUT if I do a hardware recognition in Yast (hardware info), it does work perfectly from networkmanager afterwards! 
Therefor, when yast stops quite some seconds showing âmodemâ he does something solving my problem.
Is there a way to see verbosely âwhat exactlyâ does yast during the modem recognition? I could force it to be done while starting KDE and getting rid of a lot of annoyance.
Does anybody know the âsecretâ of yast?
Using apowerpoint presentation about Yast I found /proc/modules.
How can I find out which modules are probed when yast is probing âmodemâ?
I found: pcmcia_core 39140 4 ssb,yenta_socket,pcmcia,rsrc_nonstatic, Live 0xffffffffa01f6000
This could be the pcmcia modem. How can I know? Or is this the pcmcia interface? I do not have any other pcmci adapter attached.
Not really sure what youâre asking but
lsmod shows modules that are loaded but this looks the same as /proc/⌠just proc is lower level and more direct. As for what module does what modinfo if youâre lucky will give you a description for the module.
As for seeing I suspect it is just loading a module which you maybe able to work out from looking at lsmod before and after. As for automagically think this has the info Kernel module configuration - openSUSE may find it is automagically using the wrong one but correcting it, which if is the case blacklisting maybe the solution.
Yes, thank you, these are very good hints. In /proc I get an enormous list of 36 pages that however make reference only twice to modemâŚand more or less tell me they are not correct. On what the system log:

I will dig into the info you gave me. The automagically thing may be a good candidateâŚ
