I have a TP-Link USB 3.0 4-Port Hub (UH400) and a Delock USB 3.0 cable, something similar to this, but only 1m long.

They both work properly at least I tested both with an USB 3.0 Kingston pendrive. The results for Windows 7 are in the following list. (I can test them with Windows 8.1, Windows 10, Ubuntu 16.04 too if necessary.)

  • motherboard -> pendrive - ok
  • motherboard -> cable -> pendrive - ok
  • motherboard -> HUB -> pendrive - ok
  • motherboard -> cable -> HUB -> pendrive - not ok

When I use the HUB with the cable the pendrive is usually not recognized, or it is recognized for a short time, I can see the files, but after a few seconds it shows me an empty drive with 0 bytes size.

I am not sure whether this is important, but I got several plugged in/out notifications when I use the HUB with the cable. At least I got that notification voice and according to the usbdeview something really happens in the background.

The USB 2.0 devices work properly. I can send data and charge them. The problem is with the USB 3.0 devices only. At least by this pendrive. I don't have any other USB 3.0 device.

Any idea how to fix this?

  • @Ramhound Why do you think this is a power issue? – inf3rno Nov 28 '16 at 16:35
  • @Ramhound The hub has only one short input cable. I did not get any extension cable with it and the shop did not mention anything about external cable. I am not sure about the power issue either, I can charge USB2 devices pretty well with it and transfer data as well, I have the problem only with the USB3 pendrive, which does not require much power. – inf3rno Nov 28 '16 at 17:33
  • @Ramhound As I already wrote, it works when I plug the pendrive directly into the motherboard, when I plug the pendrive into the extension cable and when I plug the pendrive into the HUB. The only scenario it does not work when I plug the pendrive into the HUB and the HUB into the extension cable. The HUB's input cable is too short, that's why I need an extension cable. Everything is USB 3.0. I am out of ideas... :S – inf3rno Nov 28 '16 at 18:04
  • @Ramhound I am not sure. I already got driver issues by a camera using an extension cable different from the manufacturer's. So I think the problem is with the cable. Any idea how to tell? I don't have another extension cable or HUB. :S – inf3rno Nov 28 '16 at 18:12
  • I can't help you. I will be removing my comments. – Ramhound Nov 28 '16 at 18:13

This is probably a motherboard related issue. The same hub with the same extender works properly on a different motherboard. I am not sure why.
