Hi! I recently acquired a D-Link DPH 50U Skype adapter and have been trying to get it working with skype on linux, but I'm a little unsure how to proceed. So why am I on the linmodem list? My current understanding is that I can use some combination of slusb.ko, ALSA and slmodemd to get the audio working first, then see if I can get keypad/DTMF working later. The unit is a USB <=> RJ11 converter, and I've confirmed the hardware functions correctly on windows: http://www.dlink.com/products/?pid=466 root@here$ lsusb -v Bus 001 Device 002: ID 0483:7554 SGS Thomson Microelectronics 56k SoftModem idVendor 0x0483 SGS Thomson Microelectronics idProduct 0x7554 56k SoftModem Running scanModem/Modem/ModemData.txt reveals: "The modem is supported by the Smartlink slusb" So I installed 32bit libs, 32bit alsa, 32bit skype, and compiled slusb.ko and slmodemd with alsa support, using this link: http://linmodems.technion.ac.il/packages/smartlink/slusb64bit-2.9.11-20070813.tar.gz (For anyone reading this later in the archive, that .tgz, using SUPPORT_ALSA=1, causes linking errors on AMD64. You need to fiddle with modem/Makefile to get it linking correctly.) Now when I load the kernel module slusb.ko, I get an unsupported codec error: root@here: modprobe slusb root@here: dmesg [33800.101765] ST7554 USB Modem. [33800.103091] st7554 probe: unsupported codec st75951/2. ok, so I hack up the driver and recompile (!!!), and now I get: [33800.101765] ST7554 USB Modem. [33800.103091] st7554 probe: unsupported codec st75951/2. [33800.103096] **hack** ignoring unsupported codec **hack** [33800.117899] <6>slusb: slusb0 is found. [33800.117921] usbcore: registered new interface driver ST7554 USB Modem Great! root@here# slmodemd /dev/slusb0 SmartLink Soft Modem: version 2.9.11 Sep 9 2008 22:32:22 symbolic link `/dev/ttySL0' -> `/dev/pts/1' created. modem `slusb0' created. TTY is `/dev/pts/1' Use `/dev/ttySL0' as modem device, Ctrl+C for termination. (I haven't tried actually using the modem to dial out yet as I expect the missing codec will cause it to fail.) ...Okay, so now I'm stuck, no matter what arguments I pass to slmodemd, I can't get ALSA to recognize /dev/slusb0 or the ST7554... root@here: slmodemd --alsa error: mixer setup: attach hw:1 error: No such file or directory ALSA lib ../../src/conf.c:3952:(snd_config_expand) Unknown parameters 1 ALSA lib ../../../src/pcm/pcm.c:2145:(snd_pcm_open_noupdate) Unknown PCM modem:1 error: alsa setup: cannot open playback device 'modem:1': Invalid argument error: cannot setup device `modem:1' I don't mind debugging / writing code / stripping binary blobs / whatever, but at this point, I just don't know what path I need to follow to get this device recording and playing audio... Do I use slusb.ko? ALSA? should I follow up the MC'97 leads? Any help would be greatly appreciated.
