I'll preface this answer by saying I haven't used cdc-acm but have a quick look into it. Your question piqued my interest because I battled with the USB->Serial adapters a while back (some of them just didn't work) > Could someone tell me where to find this driver, how to install and how > the Terminal may be used to exchange program information. > Note; I have yet to connect the device (it's still being constructed) > and so I have not tried a hardware driver search. > Geoffrey > > It appears that the module is supplied with the standard Lucid kernel. $ find /lib/modules/$(uname -r) -name "cdc?acm*" /lib/modules/2.6.32-32-generic/kernel/drivers/usb/class/cdc-acm.ko and there is documentation at http://www.kernel.org/doc/Documentation/usb/gadget_serial.txt I tried loading the module as suggested in that document and it loaded the cdc-acm module $ sudo modprobe g_serial $ lsmod | head Module Size Used by cdc_acm 18018 0 g_serial 22434 0 dummy_hcd 17058 1 g_serial and created the device $ ls -l /dev/ttyGS0 crw-rw---- 1 root dialout 251, 0 2011-06-24 08:08 /dev/ttyGS0 Then you'd need to use something like minicom or some other program to speak the appropriate protocol over that device with the other end on the device you are constructing. Unfortunately, I don't seem to have a suitable cable to test this out. -- Regards ...Peter -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
