For anyone reading this in the archives trying to get your DPH-50U to work with skype on linux, the slmodemd and slusb.ko route seems to be a dead-end. There seems to be no way to access the audio from //dev/ttySL0 . I spent some time investigating the alsa USB driver: snd-usb-audio.ko. This too is a dead end. The ALSA driver attempts to access the "Audio (non-midi)" USB protocol, which corresponds to bDeviceClass 0x01. http://www.linux-usb.org (use lsusb -v to find your bDeviceClass) I'm currently investigating the kernel usb driver, cdc-acm.ko which corresponds to bDeviceClass 0x02. (More details in kernel/Documentation/usb/acm.txt ) Will report back when I know more. (Of course, any help is greatly appreciated.) Cheers, --Chris p.s. I also located this: http://www.pcausa.com/Utilities/UsbSnoop/default.htm Don't know of how much use it will be. ========= Original Message =========== Sat, 13 Sep 2008 00:43:56 +0000 Hi Marv, > ... /dev/ttySL0 virtual ports are not Sound competent yet ... Yes, this is my understanding too. Hence, can someone help me get ALSA working with my DPH-50U ? 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' As mentioned previously, I'm comfortable debugging and/or coding - I just don't know in which direction to proceed, or which sources I should be modifying. Thanks, --Chris ============ Original Message ================== Chris, RE: trying to do: Get ALSA to identify my DPH-50U as an *audio* capture&playback device: ---------- To the best of my knowledge, /dev/ttySL0 virtual ports are not Sound competent yet, though it is planned for the future. What fixes did you have to do to the slmodem package? It they are generally needed, the package should be updated. The compile is OK on my system: /slmodem-2.9.11-20080817$ ls drivers/*.ko drivers/slamr.ko drivers/slusb.ko MarvS On Thu, Sep 11, 2008 at 5:18 PM, Chris B <striek5@xxxxxxxx> wrote: > Hi Marv, > > Thanks for your help! > > root@here# uname -a > Linux here 2.6.24-19-generic #1 SMP Wed Aug 20 17:53:40 UTC 2008 > x86 64 GNU/Linux > > Distro: Ubuntu 8.0.4 (up-to-date as of this morning) > > slmodem: > http://linmodems.technion.ac.il/packages/smartlink/slusb64bit-2.9.11-20070813.tar.gz > (compiled locally, some minor tweaks for 64bit and missing codecs) > > root@here# wvdialconf > Editing `/etc/wvdial.conf'. > > Scanning your serial ports for a modem. > > Modem Port Scan<*1>: S0 S1 S2 S3 > WvModem<*1>: Cannot get information for serial port. > ttySL0<*1>: ATQ0 V1 E1 -- OK > ttySL0<*1>: ATQ0 V1 E1 Z -- OK > ttySL0<*1>: ATQ0 V1 E1 S0=0 -- OK > ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 -- OK > ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 -- OK > ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK > ttySL0<*1>: Modem Identifier: ATI -- SmartLink Soft Modem > ttySL0<*1>: Speed 4800: AT -- OK > ttySL0<*1>: Speed 9600: AT -- OK > ttySL0<*1>: Speed 19200: AT -- OK > ttySL0<*1>: Speed 38400: AT -- OK > ttySL0<*1>: Speed 57600: AT -- OK > ttySL0<*1>: Speed 115200: AT -- OK > ttySL0<*1>: Speed 230400: AT -- OK > ttySL0<*1>: Speed 460800: AT -- OK > ttySL0<*1>: Max speed is 460800; that should be safe. > ttySL0<*1>: ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0 -- OK > > Found a modem on /dev/ttySL0. > Modem configuration written to /etc/wvdial.conf. > ttySL0<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0" > > > And here's what I'm trying to do: Get ALSA to identify my DPH-50U > as an *audio* capture&playback device: > > root@here# arecord -l > **** List of CAPTURE Hardware Devices **** > card 0: IXP [ATI IXP], device 0: ATI IXP AC97 [ATI IXP AC97] > Subdevices: 1/1 > Subdevice #0: subdevice #0 > {...I need the DPH-50U device listed here too...} > > That is, I'm trying to use my generic RJ11 phone with VOIP. > > Thanks, > --Chris > > ========= Original Message =============== > > Chris, > > Please what it your kernel version > # uname -r > and Linux Distro. > > Under Linux, slusb.ko will not compile after 2.6.24 kernels. > What slmodem package are you using? > > after the > slmodemd -c USA /dev/slusb0 > > open a 2nd console and try > # wvdialconf /etc/wvdial.conf > > MarvS > > On Wed, Sep 10, 2008 at 10:26 AM, Chris B <striek5@xxxxxxxx> wrote: >> 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?
