Hello all,
We are trying to configure the DM816x USB0 as a serial device to configure the cell modem which we connected.
We are able to configure the USB in host mode and enabled CDC ACM modem driver as mentioned in the below document
http://processors.wiki.ti.com/index.php/Usbgeneralpage#USB_CDC-HOST
Booted the board with compiled uImage.
We are able to see the device in /proc/devices as "166 ttyACM".
But in /dev we didn't get any device created "/dev/ttyACM ".
We tried to create the device with the following command "mknod /dev/ttyACM0 c 166 0" and tried to open the device using "microcom". we get the following error
# microcom -s 9600 -X /dev/ttyACM0
microcom: can't open '/dev/ttyACM0': No such device
Can anyone tell me what mistake are we doing?
Thanks,
Srikanth.
