I am trying to do "insmod" usbserial.ko and ftdi_sio.ko modules into ardrone2. Here are the details:
Sorry for French, I had to use google translator to decode it
Compilation went smooth. But when I do "$insmod usbserial.ko", I get this error message at the terminal (same with ftdi_sio):
insmod: can't insert 'usbserial.ko': Invalid argument.
Strangely the "dmesg" gives the message:
"usbserial: module is already loaded" and "Spurious irq 95: 0xffffffdf, please flush posted write for irq 56"
Same with ftdi_sio.ko
The two modules are definitely not loaded as "lsmod" or /proc/modules does not list them. I took good care of matching the linux kernel versions and the EXTRAVERSION tags. Any comments on how to do this correctly?
