Serial_install not working

[mariusl]

Hi
I had to start from scratch with all my dev stuff as I had my laptop liberated. Now I am having all kinds of issues that was never a problem before.
My USB Serial port is not recognized when I plug my Teensy3.0 in. I then tried to oload the drivers with the serial_install program but that gives the attached error. All the other serial configs work with the Teensy3.0, just the USB Serial is broken.

Oh and I am using Windows 8.0 now

You need to reboot to the special Windows 8 mode that temporarily allows unsigned driver install.

Hi Paul,
I did that before. Does it only last for one reboot?

 

[PaulStoffregen]

Correct. It only allows unsigned driver install for that 1 boot. As soon as you reboot normally, you're back to the normal settings that don't permit unsigned driver install.

OK that sorted it out. Now the question is why did I loose it in the first place? Did I do something stupid somewhere?

 

[PaulStoffregen]

Oh if only I knew why things mysterously work, then don't work, then work again on Windows....

Paul,
I gather that this wont be a problem on Linux then. I will not need a driver am I right?

Under Linux, you will need to update the udev rules to tell the udev device manager when you plug in a Teensy 3.0 what type of device it is:

sudo cp 49-teensy.rules /etc/udev/rules.d/

There are also these tips in the install page: http://www.pjrc.com/teensy/td_download.html#linux_issues

Yes, what Michael said.

The udev rules are needed because the default for unknown devices is root-only permission. The Gnome Modem Manager also needs to be told to leave Teensy alone, so even if you run everything as root, you still need the udev rules.
