Re: [beagleboard] USB3 on BBAI

['Roger Quadros' via BeagleBoard]

David,

Does the USB1 automatically switch to host mode when you plug the type-C 
adapter?
Can you please print the kernel log without the adapter connected and then plug 
the
type-C adapter?

Looking at device tree (usb1 dr_mode = "otg") I assumed that the type-C was 
designed for
both device and host cases but it looks like it was never designed to be used 
as a host as
there is no VBUS regulator for the type-C port.

The safest way to provide power to the peripheral is like what Robert suggested
- Use a *powered USB3 hub and connect your camera to that

Has anyone successfully gotten the USB3 to work as a host? If so, how?

You would need some sort of adapter or hub with power to supply your device

The BBAI needs power from either USB Type-C or (+5V) P9.5, P9.6 and (0V) 
P9.1, P9.2.

The USB2 can supply power to a device.

Yes, I'm connecting the camera to the Type-C port. The camera has a Micro B 
connector so what I have right now is a cable with a USB Type-C on one end and 
a Micro-B connector on the other side. Unfortunately my laptop doesn't have a 
USB Type-C connector so I can't check it on my own laptop. The camera supports 
USB 3 according to the manufacturer.


This is not the right way of connecting a device to the Type-C 
port. You will need a Type-C to Type-A adapter to connect non type-C 
peripherals.
The Adapter is important because it will tell the Type-C logic on 
the board to switch to DFP (Downstream facing port mode) and so turn on VBUS.

You should not need to run the script. AFAIK the port is in dual-role mode 
"otg" and should automatically switch to host on connecting the right adapter.
In case you have a type-c thumb drive you should be able to test 
this out.



My Apologies, I was incorrect on P5, it's connected to P9, the cape 
connector on the same side of the board as the Type-C connector.

Your point that the camera should be able to take power from USB 
Type-C connector perhaps could be pointing to an issue. I'm not able to get any 
power out of that port. Is there some setting I have to make, or a jumper or 
something to get that to work? Mine seems to only take power in on the Type-C 
connector.


Right. That's why you need to use the type-C to type-A adapter.

How are you connecting the camera to the Type-C port? Does the 
camera support Type-C?
If not what type-C to Type-A adaptor are you using? Does it 
support USB3.0? Did you verify it with your laptop's type-C port for example?

Re: [beagleboard] USB3 on BBAI

[robert.sty...@gmail.com]

Sorry replies crossed.

The BBAI has a TUSB322IRWBR chip to monitor VBUS, CC1 and CC2 -- it detects 
power (signalling), cable orientation (DIR) and power from (ID) (host?) 

So hardware wise may be the VBUS = 0, and CC1 (or upside-down CC2) set to 
indicate device, that USB 3 Type A socket should signal it is a device to 
the BBAI

Otherwise it is software/driver problem

Hi Roger,

That's exactly the one I'm using actually. This gives power to the device,
but it's still not recognized by the device.

 Camera should be able to take power from the USB port. Why the custom

Re: [beagleboard] USB3 on BBAI

[David Nolan]

Hi Robert,

For me I've powered the device on P9.5 and P9.1, as you've said, and
connected a powered USB hub to the Type-C also. In this scenario my camera
gets power, but is not seen by the BBAI (same for a USB key). When I do a
lsusb, it just shows the USB hubs (internally) as if nothing is connected.
When I connect to the USB 2 port everything works as expected.

Has anyone successfully gotten the USB3 to work as a host? If so, how?

Appreciate all the help,

Thanks,
David

 How are you connecting the camera to the Type-C port? Does the camera
 support Type-C?
 If not what type-C to Type-A adaptor are you using? Does it support
 USB3.0? Did you verify it with your laptop's type-C port for example?

 connected. I know the camera works as if I connect it to the USB2 port it
 all works perfectly.

 What is P5?

 Camera should be able to take power from the USB port. Why the custom
 power connection?

>From what I can see on the schematic, there is no way to power a USB device 
plugged into the BBAI USB Type-C socket, there is no path to switch +5V 
power to the Type-C socket VBUS.

You would need some sort of adapter or hub with power to supply your device 
(and the BBAI see below).

The BBAI needs power from either USB Type-C or (+5V) P9.5, P9.6 and (0V) 
P9.1, P9.2.

The USB2 can supply power to a device.

Re: [beagleboard] USB3 on BBAI

Hi Roger,

I finally got a Type-C to Type-A adapter but when I connected it, I still 
get no power to my camera, or to a USB Thumb Drive. Is there some setting I 
need to change to get this to work perhaps? 

Thanks,

This is not the right way of connecting a device to the Type-C port.
You will need a Type-C to Type-A adapter to connect non type-C
peripherals.
The Adapter is important because it will tell the Type-C logic on
the board to switch to DFP (Downstream facing port mode) and so turn
on VBUS.

You should not need to run the script. AFAIK the port is in
dual-role mode "otg" and should automatically switch to host on
connecting the right adapter.
In case you have a type-c thumb drive you should be able to test
this out.

  


My Apologies, I was incorrect on P5, it's connected to P9,
  the cape connector on the same side of the board as the Type-C

Right. That's why you need to use the type-C to type-A adapter.

Re: [beagleboard] USB3 on BBAI

[David Nolan]

Hi Roger,

Thanks for your email. Apologies for the delay getting back to you. Yes,
I'm connecting the camera to the Type-C port. The camera has a Micro B
connector so what I have right now is a cable with a USB Type-C on one end
and a Micro-B connector on the other side. Unfortunately my laptop doesn't
have a USB Type-C connector so I can't check it on my own laptop. The
camera supports USB 3 according to the manufacturer.

My Apologies, I was incorrect on P5, it's connected to P9, the cape
connector on the same side of the board as the Type-C connector.

Your point that the camera should be able to take power from USB Type-C
connector perhaps could be pointing to an issue. I'm not able to get any
power out of that port. Is there some setting I have to make, or a jumper
or something to get that to work? Mine seems to only take power in on the
Type-C connector.

Thanks,
David

Re: [beagleboard] USB3 on BBAI

Hi David,

Hi there,

How are you connecting the camera to the Type-C port? Does the camera support 
Type-C?
If not what type-C to Type-A adaptor are you using? Does it support USB3.0? Did 
you verify it with your laptop's type-C port for example?



I've run "sudo /opt/scripts/boot/bbai_usb_host.sh" to change the USB port from 
a client into a host. I'm powering my camera from the 5V on the beaglebone on P5, pin 8. 
However the camera is not getting detected when connected. I know the camera works as if 
I connect it to the USB2 port it all works perfectly.


What is P5?

Camera should be able to take power from the USB port. Why the custom power 
connection?

it. Has anyone experienced this issue before and if so, how did you get around it? Any 
help you can give would be much appreciated.


No. That line is harmless. It just says that the XHCI driver doesn't undrestand 
the LPM mechanism so LPM will be disabled.
(LPM->Link power management)

The issue is more about signal integrity at 3.0 speeds or power sequencing of 
the camera.

cheers,

[beagleboard] USB3 on BBAI

[Dave]

Hi there,

I'm trying to connect a USB3 camera I have to the BBAI (uname -r gives 
4.14.108-ti-r131). 

I've run "sudo /opt/scripts/boot/bbai_usb_host.sh" to change the USB port 
from a client into a host. I'm powering my camera from the 5V on the 
beaglebone on P5, pin 8. However the camera is not getting detected when
