Number of USB ports

HI,

Is there a limitation on number of USB ports that could be plugged through a USB hub into one USB port of Anywhere USB?

My setup is like, USB hub → port 1, USB hub → port 2…. USB hub –> Port 5. Each USB hub is a 10 port type, all 10 ports being populated with USB2.0 devices.

All these are USB 2.0 types.

I am using a 8-port Anywhere USB.

In the above setup, I am actually trying to connect total 5 USB hubs. the moment i connect more than 3, the 4th and 5th one are not visible in the Anywhere usb software.

Please let me know if anyone has a solution.

Thanks.

Hi there,

I think this setup is within USB spec.

Are the downstream (10 port) USB hubs self powered, or are they bus powered? Self powered meaning they use their own power adapters, bus powered meaning they only have upstream USB cables (no power adapters)?

What kinds of USB devices are attached to the 10 port hubs?

What OS is the computer running?

If this is a Windows environment, is there anything in Device Manager with any warning icons related to this setup?

HI,

These are self powered USB hubs. They dont draw any current from the line. These are USB 2.0 hubs. My PC is running Windows 11 and we see warning signs in the device manager against these ports.

Does it fall into any category of problems you had seen in the past? Or you have a suggestion to try out? please let me know.

Thanks.

What are the specific errors you’re seeing in Device Manager (if you double-click on the devices with the warning signs)?

And are these errors specific to the USB devices attached to the 10 port USB hubs, or are they for the 10 port hubs themselves?

What happens if there are no USB devices plugged into the 10 port hubs, are there any errors in Device Manager then?

Hi the picture shows the errors. All those devices has the same kind of errors. If i dont plug in any device, nothing appears.

Good afternoon,

Some suggestions:

  • Try one or more others PCs (maybe even one running Win 10), to get more data points.
  • Download USB device tree viewer, to try to find out how many endpoints are being used.
  • What happens if you start with nothing connected to the AWUSB, then you plug in just one empty 10 port hub? Then add a second? When does this “break” specifically, in other words?
