I have a USB A hub, but it does not get power when using a a USB C to USB A cable; do I need a powered hub or a special cable?
 
What exact hub make and model?

"This SuperSpeed USB 3.0 hub supports data transfer up to 5Gbps, do not support charging" (sic!)
 
I am not after charging, I am after the hub being powered.
 
What exact pc connected to? Should be connected to the back I/O
 
Tried it on an HP all in one; no luck.

This is all in anticipation of an iMac I should soon get (at work)

Oh, that. Almost any cable should do, but USB-C has so many capabilities, often the cable manufacturers only wire what they want :(
 
That's too much USB ah ha but it has a power adapter so that's good
 
Thanks to all, this has been most helpful.
 
Not all projects pan out; you helped me figure this one was barking up the wrong tree and that a new hub is now justified.

Seems the 10 port (powered) version is $20 on ebay (with postage); it doesn't have the USB C to A cable, but I do.

No space grey version... but I'll survive :)

I thought it would be enough to used a powered hub, but that didn't work.

And yet... this should have worked
The Best USB and USB-C Hubs | PCMag

AUKEY Powered USB 3.0 Data Hub with Power Adapter​

The sleek white design of this Aukey USB data hub is unobtrusive and complements the look of most setups. Ten vertically oriented USB 3.0 ports transfer data at up to 5GBps. The hub connects to your laptop via a detachable USB-3.0-A-to-A cable; if your laptop only has a USB C port, this cable could be swapped out for a USB-3.0-A-to-USB-C cable, at your own cost.

Wth, what didn't work this time?
 
I moved to a powered hub
 
I may be incorrect but, I'm fairly certain proper USB-C uses 'both sides' of the flip-able connection for power (and data).
It's likely, what you're plugging it into (the PC/Mac) was the issue.

Did the externally-powered hub resolve the issue(s)?

If this comes up again in the future, there are 'power injecting' USB cables (that 'dongle-off' a DC power jack or another USB(power only).
 
Unfortunately moving to a powered hub did not help; that is why I returned here.

You lost me. The original problem was the hub wasn't getting any power. Now you're telling a powered USB also isn't getting power? (Obviously I'm missing something.)
 
  • The original hub wasn't getting any power.
  • The new hub is getting power (obviously) but the computer does not see anything connected; while the hub works just fine when running A to A; I have tried on a Mac and a PC
I actually got sent the wrong hub; I ordered the Aukey CB-H6, but received the CB-H6S which only has 7 of the 10 ports for data.

I was able to update the firmware of the original (4 port) hub, but not this one. Figured out the GL3520 chip has 4 exit ports (my original hub), so when stacking two chips that makes 7 ports (what I have now), or 10 ports with 3 chips (what I ordered).

I took the risk as I can still use it in A to A mode (and the price was good), and have written to Aukey to see if they have any idea (I tried several USB C to A cables).

At this point I am just asking my work place to get me a more recent 10 port hub and will see what the seller says.

F me sideways...
I know there used to be a problem where a hub would split the current over the available ports so devices wouldn't get enough juice, but you'd think a powered hub doesn't have that problem. Actually, since you say it works otherwise, it probably doesn't. Not sure what would make it invisible to a PC :(
 
It's a 48W supply so I don't think that is the issue.

The intpw picture shows an A to C cable, so that one should work, but it costs more than twice as much as the old Aukey.

Must be something fishy about these, it seems Aukey doesn't even do USB hubs anymore. And the user manual is a joke...
 
Forgot to mention, my 4 port Aukey CB-H5 was on firmware 9224 for the GL3520 and I updated to 9226; this unit is firmware 0655 for the GL3520 of which there seems to be no mention on the web and all attempts to update fail.

Will see what the seller does about having sent me the wrong unit (the CB-H6S instead of the CB-H6 advertised)

For me it's about trying to figure things out with an aim to having a usable end product.
