Hello all-
We are attempting to get Tinyusb running in host mode on an STM32F411 working with the MAX3421 host controller. The STM32 is on the STM32-F4 Discovery board from ST and the MAX3421 is on the SparkFun Arduino shield. Our project is in a state that if we attach a CDC device to the shield data is successfully passed back and forth. However our project requires multilevel hub support. So far we have failed to get even one hub working correctly. There are two that we test with from J5 Create, model JUH470 and model JCA374. The model JUH470 sometimes causes errors on attachment.

Here's a good output dump-

sizeof(tu_fifo_t) = 12
sizeof(tu_edpt_stream_t) = 24

Hello,
I have almost the same setup (stm32f7xx as host, MAX3421E, hub and several CDC devices) and the limitations of the hubs are known.
According to docs/reference/index.rst only one hub level is supported so far.

Thanks! Since multilevel hub support is a sine qua non for us we should stop spending anymore time working with TinyUSB, especially since we already have issues getting just one hub running correctly. We won't have time in our project to both investigate those issues plus add the multilevel support on our own.

By the way, I'm currently working on expanding the CDC host. You are welcome to test it: #2488
