Hi everyone,
for a project I need to control a few different systems with the host serial of teensy.
Among these systems I will have to be able to control another Teensy with a Hub.
I soldered a usb connector to the USB host pins of my master teensy. And can recognize successfully some commercial USB thermometers and hubs.
I am using the library USBHost_t36 with the exemple USBHost_t36/Test/SerialTest.ino
If I plug a hub and my thermometer (which send the line #CT periodically before I unplug it in my test). The program recognize it without any problem.
Code:USB Host Testing - Serial *** Device Hub1 1a40:101 - connected *** product: USB 2.0 Hub *** Device Hub2 1a40:101 - connected *** product: USB 2.0 Hub #CT #CT #CT *** Device USerial 483:5740 - connected *** manufacturer: STMicroelectronics product: STM32 Virtual COM Port Serial: CT000 #CT #CT #CT #CT *** Device USerial - disconnected ***
But when I try to plug another Teensy to my USB host nothing happen. (same thing with the HUB or without).
I digged a bit in the code and uncommented the line :
//#define USBHOST_PRINT_DEBUG in USBHost_t36.h to get a bit more informations. When I plug the teensy I get:

For comparison if I do the same with the termometer I get that:

It looks like some descriptors (Descriptor 36 = ???) are not recognized and the program just loop trying to get the missing informations.
If someone has an idea how to proceed from here it would be helpful.
Thanks
