Thanks for your continued help and good advice. I try to use the Teensy core without modifications by me. For my use it is better if I put the potential infinite loop into my code rather than in the USB core. Taking the lessons from above, I...

Thanks, I'll take a look at the USB serial code and see if there is anything I can tweak. But as you say, without any kind of flow control, transmitting faster than the receiver operates will lead to problems. Agreed on the state of WIndows...

I have been trying to find a solution using the new insight about USB serial on teensy3. So far, no success. If I check the value of Serial.availableForWrite() and wait for it to be 64, the program hangs until watchdog reset about 80 seconds...

In the Teensy cores, all of the directories, directly under cores with the name USB_ are for Teensy 2.x (maybe 1.x as well) only At times I wish we would split this up into a couple of different installs, like 2.x and 3-4x... But... The USB...

Thanks Paul, I appreciate the explanation. I understand the evolution of the code following the evolution of the microcontrollers used in the Teensy series. I'm very happy with the teensy4 approach. Now that I understand the philosophy used for...

I have numerous applications that store data in files on the SD card. One feature of the program is to print the file to the USB serial interface. "Because of Windows", and in particular "because of usbser.sys", I have to put code on the Teensy...
