Teensy 3.5, Windows 10. Arduino 1.8.12. Teensy loader 1.52. Code is "blink" from example library, with delay parameter changed to 200. I have tried several cables, USB ports, three different windows computers. I have read the FAQ's, tried rebooting and plugging while pressing button. Tried only this one chip though.
Pressing the Teensy button results in maybe a little shorter "off" cycle in the blinking only once and then it goes back to 0.5 Hz blinking. After a second comes three notes from windows like when unplugging a USB device. Even when holding the button down the blinking continues.
Error message from arduino IDE is
"Teensy did not respond to a USB-based request to enter program mode.
Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch."
Only one action have had any effect. If I hold the teensy button pressed while trying to load the program the blinking stops! After a while I get:
"error sending reboot command (HID)"
and the the same error message as above.
Any help would be highly appreciated.
