My Hub don't detect the miners antminer u2

[yoandrey]

I have a powered hub and the hub don't detect the 2Xantminer u2 ,both antminers work perfectly directly connected to the ports of the pc ,what to do ?

What hub model?

How many Amperes does the power supply of the hub provide?

Are your PC ports USB3?

[yoandrey]

No my pc don't have 3.0 usb , the hub is this one http://www.amazon.com/AmazonBasics-Port-2-5A-power-adapter/dp/B00DQFGH80/ref=sr_1_1?ie=UTF8&qid=1411135908&sr=8-1&keywords=amazonbasics+usb+hub+3.0, I'm almost sure that the problem is with the drivers .

The hub doesn't need drivers. If your miners work when plugged in directly to the PC, the problem is likely to be with the hub. Does other equipment like a flash drive work on the hub?

check to see if they show up in device manager.
sound more like a power issue to me but more info will be useful

There is a decent chance of this look at model of hub and power.  Most hubs were not built with mining in mind.  There are some that work and have a good amount of power.

If you have right power then check hub with something else such as usb thumb drive.

If drive works look into drivers.

Hopefully between power and drivers you will fix it.

Hub working perfectly with other devices , when I connect the usb miner in device manager I see Unknown Device , I don't think that power is a issue .

sorry to say its looking like it is a power issue. thumb drives and stuff use at most 20% the amount a usb miner does. id be willing to bet either the plug dosnt put out enough current or the hub its self is loosing the current internally.

youve tried them directly in the usb port and they worked so theres only the hub that could be the problem.

options are
1. buy a new powerful hub
2. buy a new powerful mains adapter
3. buy a Molex to Barrel jack so the hub plugs directly into you computer PSU i have a few spare but im in the UK

I had the same problem with my U2s. I replaced my 3.0 hub with a 2.0 and now my U2s work fine.
