Blue Screen in connection with Teensy 3.1 and KORG SQ-1

Hello,

I have a problem with the Teensy USB Driver!

My PC System:

Win7 64 Bit and
Arduino 1.6.12
Teensyduino, Version 1.31
Korg Driver 1.15.16.2


I always have a Blue Sreen in connection with the Korg SQ-1!

https://www.korg.com/us/products/dj/sq_1/index.php

Is this perhaps the Teensy 3.1 USB Driver?

Unfortunately, I can not describe as good English to describe it exactly.

It all works normally under Windows!Write sketch and anything else!

Only when shutting down Windows there is a Blue Sreen.

Maybe someone can read german ??

Here is a link where I posted the problem. Unfortunately only in German !

Click to expand...

The "driver" Teensyduino installs is only an INF (text only) file which tells Windows to load its own USBSER.SYS driver when Teensy appears as a serial port. The "update driver" button merely set a flag in Windows registry device nodes to request update by the New Hardware Wizard.

Teensyduino does not install any kernel mode drivers. PJRC has never published any Windows kernel mode drivers. If you're getting a blue screen from a kernel mode driver, it's certainly a bug in someone's driver, but it can't be from Teensy since I've never written any Windows kernel mode code.

Teensy uploading always HID protocol, not Serial. If you've selected MIDI in Tools > USB Type, Teensy is not using serial at all. It's appearing as a MIDI and HID device, which don't use the INF for serial.
