There is a section of the USB user guide as follow:
multipoint/hub support (applicable for PG1.X) :
The multipoint support in musb controller IP is disabled. Due to this limitation only one usb device can be connected to one usb port and HUB cannot be supported
I don't understand the meaning, Is this to say, DM816x has two USB ports, only one USB device can be connected to each USB port, I cann't use USB hub for adding more
USB devices?
I have one USB camera, there are three usb devices inside, it can be connected into a USB port through it's own Hub, but I get the follow information when it is connected to the DM816x DVR‘s usb port:
usb 2-1: new low speedUSB device using musb-hdrc and address 21
hub 2-0:1.0: unable to enumerate USB device on port 1
It cann't detect the USB device, I don't know why
