Difference in performance on USB-C from an USB-hub; connection via adapter USB3.1-to-USB-C or direct connection


Recommended Posts

I'm having an Anker 4-port USB 3.0 Ultra Slim Data Hub (USB 3.1) (causing interference with my mouse).

 

I can connect the USB-hub to an adapter USB3.1 to USB-C (see pic with the 'B') and plug it in my computer, and have the USB-dongle for my mouse be in the generic USB 3.1 port.

 

My question performance wise (and maybe even also 'power wise'): is it better to have a "native" USB-C type usb-hub? Or can I also use an adapter from USB-C to USB 3.1 and have the same performance?

I would like to have this USB-hub powerless/no power supply.

 

In case of a direct connection a new USB-hub has to be bought by me (like e.g. this Satechi as attached)

The difference is negligible as long as the adapter is the same speed/usb version as what is plugging into it.

OK. So USB3.1 device/hub into this adapter still brings it (down) to USB3.1. I get that ;)

So, technically it's better to have a 100% USB-C usb-hub, like e.g. the Satechi I posted here).

The devices connected to, determine the actual speed/throughput. But USB-C has a higher bandwidth, so technically my connected HDD and running device (when connected) can operate on full speed.... 

USB-C doesn’t have a higher bandwidth if it’s backed by the same tech as the USB-A ports. It’s just a different connector at that point.

I see that "A USB-C port equipped with Thunderbolt 3 can push data speeds to a theoretical limit of 40Gbps. To show how far we've come, that's four times faster than USB 3.1"

 

So, maybe even when connecting USB3.1 (10Gbps) the 'internals' of the USB-hub are I guess "more equipped" to handle these speeds.

("simplified": 4 USB 3.1 devices of 10Gbps = 40 Gbps; instead of a USB3.1 USB-hub which gives more or less 2.5 Gbps (maybe maxed out to 5Gbps) if not all are on full load per port (10Gbps/4 ports is this 2.5Gbps)

 

Or does this kinda tech in usb-hubs work differently?

Nah.

 

The controller is what matters here. If all of your controllers are USB 3.1, you get the same bandwidth regardless of connector type. If your USB-C is Thunderbolt, then thats different.

The specs on Satechi's site lists: "CONNECTOR TYPE Type-C, Thunderbolt 3 Compatible"
Than the question... is my notebook Thunderbolt 3 Compatible?! Have to look that one up ;)

You're right on that one. The manual states: USB 3.1 Gen 2 Type-C, transfer rate up to 10 Gbps.

So... I can just use this adapter than?! And safe myself almost a 100 bucks.

You can; but if you run out of power for the devices or see malfunctions due to lower power, you will know why.

Yeah I know (mouse issues). But this one is not on the same USB-ports input on my mobo.

So, (hopefully) the internal power relay to these USB ports (type A & type C) are different... and therefore causing -probably- less issues.

Regarding your mouse interference ... nothing to do with the power on the A or C ports. 5 and 10 Gbps USB speeds  generate a lot of RF energy in the 2.4GHz spectrum. Poor shielding on devices or having these 5/10Gbps devices operating very close to a 2.4GHz receiver will cause issues. Physically separate them.

Thx.

So, my assumption could be correct as the 2.4Ghz dongle is place next to the USB-port of the USB-hub, and hence the interference.

And... using a completely different (USB-C) port on another side of the notebook making the distance larger and, therefore, causing less interference due to the distance between the plugged in 2.4Ghz receiver and the via USB-connected usb-hub.

When I had my Logitech unifier wireless dongle, it never worked correctly in the back port, so what I did is I got a 6ft USB extension cable, plugged it in the same port and then ran the wire and taped it to the back of my screen, mouse and keyboard worked great after that.

I looked up an overview of this Asus GL731V notebook, and came across this video.

The image a still from it.

 

Looks like the connectors are wired to a different part of/on the motherboard, so with the usb-hub plugged into the USB-C port (above in picture), and the mouse-dongle in the 'regular' USB (part of the port-of-3) (right-side op picture)  I think I'm better off...

    • Google Workspace now lets you use custom AI Gems directly in Docs, Gmail, and more by Paul Hill Google Workspace users can now access Gems from the side panel of Google Docs, Slides, Sheets, Drive, and Gmail. Previously, Gems could only be accessed from the Gemini app directly. For anyone not familiar with Gems, they’re a more advanced feature in Gemini where you can make your own chatbots, powered by Gemini, with custom instructions. If you’re interested in learning more about them, check out my editorial from April, where I argue custom AI bots are the best thing about generative AI and how to create your own bots. The decision to make Gems available across Google Workspace has the potential to significantly speed up people’s workflows if they’ve started using Gems already. If you’ve never made a Gem, Google has several pre-made ones including a Brainstormer, Writing editor, Coding partner, and Learning guide. Google Workspace users can leverage Gems in an almost infinite number of ways. For example, imagine if you’re a teacher in whatever country and you have to make lesson plans for your class that must follow a certain structure, you can use natural language to program a gem to expect certain inputs from you (such as grade, subject, topic etc) and get an output that follows the required guidelines. If you’re a journalist, you could create a gem to quickly strip out the key bits of news from a press release or if you’re a student you can create a bot to break down complicated subjects into something easier to understand. The possibilities are nearly endless and now the Gems you make are even more accessible. Google mentioned that Gems can be accessed via the side panel of all supported Workspace applications and can be used across Workspace capabilities including @ mentioning, accessing files and folders, and more. If you need to create a Gem, you’ll still need to do that on the Gemini website. To get started with Gemini in Google Workspace, just click the “Ask Gemini” (spark button) in the top-right corner. Google said that the Gems feature rollout is an extended rollout which means it might take more than 15 days to get the feature. Admins out there do not need to do anything and there are no specific admin controls in the side panel for Gems or Gemini.
    • Microsoft changes hit Teams Android devices: Disable Entra ID policy to restore sign-in by Paul Hill As part of its Secure Future Initiative, Microsoft has deployed a new Entra ID Conditional Access policy targeting Device Code Flow authentication. Unfortunately, it has led some Microsoft Teams-certified Android devices (Teams Rooms on Android, Teams Phones, Teams Panels, and Teams Displays) to be logged out and signing back in can be a bit fiddly so guidance has been shared. Microsoft said that it shared previous guidance which explained how to exclude Android devices, but it seems some admins didn’t catch this as many devices were not excluded and have been signed out. It’s important to realize that this is not a bug, it’s a security feature. However, the move could have been better communicated. To sign the devices back in, you can do so manually. However, if the devices are remote you’ll need to follow these steps: By disabling the “Block device code flow” policy in step 1, it will change everything back to how it was before Microsoft decided to enable it to boost security. This will allow you to get those affected Android devices logged back in again. Also pay special attention to step 2 which says you might need to reboot your device three times. Once you have your Android devices logged in again, it’s probably a good idea to follow Microsoft’s previous guidance and add these to an exclusion list before re-enabling the “Block device code flow” policy. Microsoft recommends only allowing DCF where it’s absolutely necessary and then blocking it elsewhere. The best thing to do is to add your Teams Android device to the exclusion list - this will allow these devices to operate normally, while boosting overall security. If you’re an admin and have been impacted by this, be sure to take proactive measures to avoid disruptions in the future.
