Sorry to resurrect an ancient thread, but I wanted to chime in and say I had an identical issue as in this thread: The ATWINC module is detected with the latest firmware, but can't connect to WiFi or see any networks. The issue seemed to specifically be with connecting the IRQN pin of the...

Hey all, a simple question with a (likely) complicated answer. I just want to know if there is a way to see which specific port in a USB hub a certain device is plugged into. EDIT: Nevermind, got it! dev->hub_port For anyone stumbling across this in the future

Hi, little update to this. I redesigned the board with a new IC (TUSB2036VFR) and am actually seeing exactly the same thing on the Teensy side, it sees the hub but no descriptors or devices. I ordered a USB host cable and will try with a real hub when it arrives, but without testing a whole...

I decided to just solder a USB A connector onto the USB Host headers of the Teensy, uploaded a blank sketch and plugged it into the PC. Windows reports a "cannot get device descriptor" when I plugged something in, which actually tracks with what I was seeing on the Teensy. So must be a board...

In this case, this is is two different devices plugged into the hub. One is a raw USB HID device, and another is a USB thumbdrive (just for testing.) If I remove one of the devices, I only get one of those messages. So it seems like one device, but it's not (and both messages seem like device...

Bumping this. I'm willing to redesign with another hub IC, but is there anything specific the Teensy requires that I should be looking out for? Can someone using a Teensy with a hub post some example code/output so I can compare?

Hi! I'm working on a board with a Teensy 4.1. I have a USB hub IC hooked up to two USB ports on a custom board. The IC is a USB2412. I'm having some trouble reading devices, and I'm trying to figure out if it's my fault or something in the USB host stack. Using the HIDDeviceInfo program (with...

I'm trying to develop a way for an end user to be able to load .hex files onto a Teensy as painlessly as possible. I know this used to be possible through Teensy Loader, which seems to be very EOL. I was wondering if maybe the PJRC team would consider to open sourcing it and giving us an...
