thank you very much for your answer. when i make a dmesg i got these two lines. so i guess that the driver is present. usbcore: registered new driver cdc_acm drivers/usb/class/cdc-acm.c: v0.23:USB Abstract Control Model driver for USB modems and ISDN adapters
i appended the following two lines to the makefile under <sdk root>/packages/devices/ttyUSB $(MKNOD) -m 0666 $(DEV)/ttyACM0 c 166 0 $(MKNOD) -m 0666 $(DEV)/ttyACM1 c 166 1 unfortunately there wasn't another response when plugging the modem. in the sdk menu i didn't find an option that seemed to be necessary for the problem. probably my elsa microlink 56k fun usb modem isn't acm compliant. i flushed foxserve, plugged the modem without any modification and the response was just: crisv10_irq dbg: ctr_status_irq, controller status: host_mode started crisv10_irq dbg: ctr_status_irq, controller status: host_mode started running usb 1-2: new full speed USB device using hc-crisv10 and address 3 do these facts indicate that my modem isn't acm compliant? Or did i forgot something important? thanks --- In [email protected], Davide Cantaluppi <[EMAIL PROTECTED]> wrote: > > Hi, > It seems that the driver was not loaded because the device is not claimed... > Check the driver presence then > you have to create /dev/acm0 and /dev/acm1 so that the cdc-acm driver can > use the device, > major is 166 > minor is 0 > If i remember correctly was also added to the SDK so please check inside the > SDK menu... > If you want to add it manually modify for example the Makefile for ttyusb > inside > <sdk root>/packages/devices/ttyUSB and append to the file the $(MKNOD) for > /dev/acm0 and acm1 with major 166 minor 0. > > I suggest you to try your modem with foxserve where the CDC-ACM module is > already loaded so you can see if you device is cdc-acm compliant. > > Thank you > > Davide > > > > Il 18-06-2007 17:12, "elhobit" <[EMAIL PROTECTED]> ha scritto: > > > > > > > > > > > hi to all > > > > i got a microlink usb modem witch i would like to use with my > > foxboard. the modem should support acm. i added the cdc-acm driver to > > the kernel. > > when i plug the modem to the foxboard i got just the following message > > on the /var/log/messages > > > > kernel: usb 1-2: new full speed USB device using hc-crisv10 and address 3 > > > > when i look at the explanation under > > http://www.foxserve.it/cdc-acm.html there should happen also other > > tings when plugging the modem. also there aren't files created under > > /dev/usb/acm / like described in acm.txt > > > > i do not use foxserve. is that the reason? which are the next steps to > > make my modem running? > > > > thanks for help > > > > > > >
