Error after application terminated

[zoell]

I am running the cm160 binary in a non demon mode like: ./cm160 just to check the data coming in. If I terminate this, and try to restart it, I get the following:

zoell@srv02:~/eagle-owl/src$ sudo ./cm160
Wait for cm160 device to be connected
Found compatible device #0: 0fde:ca05 (036)
Found 1 compatible device
bulk_read returned -110 (could not detach kernel driver from interface 0: No data available)
Wait for cm160 device to be connected
Found compatible device #0: 0fde:ca05 (036)
Found 1 compatible device

And it does not do anything just retries these. The only solution I could find is to unplug/plug the usb, but this is a bit pain if I am not at home. Is there any idea on this?

@zoell I'm getting these messages when I run ./cm160. You will probably find that if you do
ls /dev/ttyUSB0
(or whatever device you Owl is at) it's vanished. You should be able to bring it back to life with
sudo rmmod cp210x && sudo modprobe cp210x
After this the device in the dev directory should have re-appeared and running cm160 may work again. It's not a direct fix for your problem but it is something you can try to bring it back to life when you are away from home.
