Not enough host controller resources for new device state

I have a Jetson AGX to which I’m connecting a board that has 6 sierra USB modems (EM7565). When I turn the modems on, the first four modems turn on fine. The fifth and sixth modems, however, show an error message in dmesg:

[  741.023961] usb 1-4.2.1: new high-speed USB device number 16 using tegra-xusb

[  741.047165] usb 1-4.2.1: can't set config #1, error -12

The problem is not specific to any particular modem, if I bring up just modems 5 and 6, they work.

Is this a known issue?

Thank you

Just for added info, here is some more info:

Successful modem’s dmesg looks like this:

The required bandwidth in USB is being exceeded. HUBs of course share a single USB root_hub’s resources. So you would need to move at least part of your devices to use a different root_hub.

Note that if you have a single USB3 camera on a USB2 port (and 480M is USB2), then a single camera would exceed resources. Possibly 2 USB3 cameras on a single USB3 port could exceed resources. Depends on bandwidth requirements.

Thank you for the reply, but I don’t think I understand it. Four unconnected modems don’t consume much bandwidth (or, at all). The failures are just too predictable.

We’ve had USB bandwidth exhaustion problems before (never on the modems, mind you). They happen under load, and they happen sporadically. A case where I can predict when things will fail does not ring like a case of bandwidth exhaustion.

And that’s before I mention that the same device, with the same 6 modems, functions fine on other platforms we’ve tried. Even a raspberry Pi 3 managed to connect and dial the 6 modems, using the same USB hub and same cable.

You could be correct, but do you happen to know if any of those modems use isochronous mode? You can look at this with a verbose lsusb (requires sudo and adding “-vvv”), and if any of it is isochronous, then it means there is a pre-allocation of bandwidth the device expects. Any inability to reserve bandwidth would be an issue, although I doubt a modem would use isochronous mode (it is probably bulk or interrupt mode).

Also, are these connected via a powered HUB, or is this powered over USB? If for some reason this was related to power delivery instead of bandwidth, then a powered HUB would fix the problem (or at least show it isn’t the problem).

It might end up that there is another limitation NVIDIA would have to comment on:

…perhaps this configuration just has a limitation at a lower value than other systems (don’t know).

I’m bumping this, as this is still waiting for a solution. If the Jetson cannot connect to 6 modems, I need an official statement that that is the case.

Are you using a Developer Kit?
There might be several ODM Carrier boards that easily support your usb requirements

I am using NVidia’s developer kit.

Links would be appreciated.

Thank you,

Hi,
Please check

On Jetson Xavier devkit, there are two type-C ports. You may use type-C to type-A adapter to connect the USB devices.

Hi Shachar,

The Connect Tech Rogue Carrier brings all three USB3.1 ports from the AGX Xavier out via USB Type C connectors:
