YES :-)!!

It's working as I write... There still some strange stuff but it works. Still had to change the timeout to (at least) 1000 in this instance.
I include the syslog and the ppd log for reference.

I'll do reliability tests as soon as I can stay close to the machine long enough (It's my server, so I need it up 24/7)

Ok, so here I am again trying to make the Elsa Microlink Usb modem working under Linux. I've been wondering numerous times why I didn't bought a supported modem or an adsl router rather than keeping this old, unsupported thingy. But, hey..., where would be the fun :-) I just wonder if someone else in the world is trying to use it with Linux...

Note that, as I didn't succeed to have ueagle working for me so far, I'm using a patched (by myself) Eagle-Usb v2.0 module now.
Note also that I'm far from a kernel guru, so any patches I could make are entirely empirical (meaning I basically don't know what I'm doing ;-)

Config:
- Gentoo 2.6.12-r6
- Elsa Microlink
- ueagle 1.0.0b

Problem reports:
0) "setting any alternate failed for 2 interface, using bulk mode"
Not a problem, a fact. Always been using bulk mode with the elsa

1) "firmware ueagle-atm/adi930.fw is not available"
Well, looks like ueagle insists that the firmware be in a "ueagle-atm/" subdirectory of the hotplug firmware lib ("/lib/firmware" for me).
Not documented or I missed it ;-)

2) "interface 2 not found"
It looks like the elsa do not have this second interface, so, when ueagle tries to claim it, it obviously fail.
I have to comment the interface claim to go further ("//ret = claim_interface(usb, usbatm, UEA_DS_IFACE_NO);")
I have no idea what these interfaces are. The point is that I had to do the same thing in Eagle-Usb and it worked like this.


3) "elsa de-reset failure (-110)"
This one is related to the loading of the xilinx fpga (ie. the singularity of the elsa).
To "de-reset the elsa", you really have to terminate with a 0x0A as the command parameter of the usb_control_msg, otherwise, no go.

u8 value=0;
ret = uea_send_modem_cmd(sc->usb_dev, 0xe, 1, &value);
//ret = uea_request_xilinx_end(sc, 0xe, 1, 0, NULL);

4) "writing cmv failed with error -110"
We're progressing. If I'm here, I assume the DSP loading worked without error.
This is were I stopped last night. Unfortunately, I'm a bit worried because I had the same problem with Eagle-Usb: CMV is not working.
I must say I didn't insisted at the time, as eagle-usb.conf worked perfectly. I hope I can find a workaround...

4bis) "usb_control_msg error -110" when executing uea_request(sc, UEA_SET_MODE, UEA_START_RESET, 0, NULL);
I'm nowhere on this one. The process seems to continue fine but could be the cause for 4).
This is strange as the code seems to be functionnally identical to eagle-usb...
