Cannot Access /dev/ttyusb
The time now is 07:54 AM. The point of the "check list" in "/var/lib/usb_modeswitch" is to make sure only a device that was handled by usb_modeswitch before is touched. Upgrading the kernel on a server is not an easy fix by any means. share|improve this answer edited Sep 27 at 17:58 tomas 2,9443933 answered Nov 28 '13 at 12:26 ganeshredcobra 20126 add a comment| Your Answer draft saved draft discarded Sign up or his comment is here

Where in the analytic hierarchy is the theory of true set theory?
All of the sudden (there was a system upgrade) it stopped working.Now I get the error message:avrdude: ser_open(): can't open device "/dev/ttyACM0": Permission denied Problem uploading to board.
However, the driver should be re-bound by the udev rules of usb_modeswitch after a warm reboot, creating the ttyUSB ports again.

I just saw this bird outside my apartment. The problem is that I can't find any device analogous to the ttyUSB0 that is created in my machine (and AFAIK, in all normal Linux boxes). Can you provide step by step instructions. However, as many different products from many different companies all use the same FTDI chip, each product is given a unique ‘product id’ number for identification purposes.
