I checked several related posts but couldn't solve my problem.
I have Antergos Linux :
# uname -a
Linux biutitude 4.14.11-1-ARCH #1 SMP PREEMPT Wed Jan 3 07:02:42 UTC 2018 x86_64 GNU/Linux
The board is a Seeeduino Lorawan.
The problem is that the menu to select the port is greyed, and when I check in /dev I don't see any new tty when I plug the card. However the card blinks.
I tried : - adding myself to lock + tty + uucp (and restarted my session) - created a dialout group because I didn't have one, added myself to it - loading cdc_acm module but got the following error :
# modprobe cdc_acm
modprobe: FATAL: Module cdc_acm not found in directory /lib/modules/4.14.11-1-ARCH
Thus I tried :
[root@biutitude biu]# depmod -ae
depmod: WARNING: -e needs -E or -F
depmod: ERROR: could not open directory /lib/modules/4.14.11-1-ARCH: No such file or directory
depmod: FATAL: could not search modules: No such file or directory
[root@biutitude biu]# depmod
depmod: ERROR: could not open directory /lib/modules/4.14.11-1-ARCH: No such file or directory
depmod: FATAL: could not search modules: No such file or directory
I'm clearly out of ideas. The weirdest is that a few months ago, I was able to use a RFduino card without any trouble.
watch lsusb
, then plug in the board. Does it show a new entry in the list? If so, what does it say?dmesg -w
is your friend. Run that, plug in the board, and look what it tells you.
