Hi Igor,

1. Just to clarify that we're talking "Multi-Point Support", i.e. that the USB controller when operating in host mode can host multiple USB peripheral devices. Please confirm.

2. How many end-points are supported?

3. Is there a driver or example project available, demonstrating multiple usb-devices running via a hub?

Thanks David

Hi Igor, I've done that, there is only very basic examples, no host with hubs.

Please reply my questions 1 & 2.

Hi David

number of endpoints is described in sect.55.1.1 Features

i.MX RT1050 Reference Manual
https://www.nxp.com/docs/en/reference-manual/IMXRT1050RM.pdf

For new questions suggest to create new thread.

Best regards

from the "i.MX RT1050 Processor Reference Manual"

• Up to 8 bidirectional endpoints

  Although there is no separate Transaction Translator block in the system, the transaction translator function normally associated with a USB 2.0 high speed hub has been implemented within the DMA and protocol engine blocks to support connection to full and low speed devices.
