The GPRS modem should connect to the USB host.
#GADGET SERIAL V2 4 DRIVER DRIVER#
How are you connecting the GPRS module to the board exactly? Are you connecting this to the USB host or USB client port? CDC ACM USB class driver would not be required since it is only applicable for USB client. If I understand correctly you want to connect the GPRS modem to the Toradex module/board.
Can you give me the output of ls /lib/modules/ĮDIT: Also refer my earlier answer as I added some more details.

I assume you followed the procedure here to update the kernel.ĭid you deploy the modules from your own kernel build? The modules installed by default in the image will not work since the kernel version tag will not match. Note that it is not required to load the g_serial above as u_serial and usb_f_acm is already loaded. Libcomposite 27376 12 usb_f_acm,usb_f_rndis What changes did you exactly make to the kernel? Anything other than the above configs?

All the required USB gadget function drivers are deployed by default as modules.
