Hi folks,
I'm struggling with a newly bought USB 3.0 PCIe card. My motherboard has only some USB 2 ports so i decided to put a PCIe USB 3 card in.
It is recognized fine by the xhci_hcd kernel module:

Kernel driver in use: xhci_hcd |
If i connect an external powered USB 3 hub, it is NOT recognized.
Instead it keeps telling me that port 1 and 4 have over-current conditions:

Even if nothing is connected to that ports it keeps telling me that.
It looks to me that the hardware is powering off the ports due to the overcurrent, but is that right?
Is there a way to overcome this and keep the ports online even if they have the overcurrent condition?
Thanks in advance!

| the only time I've seen the kernel report over-current on a usb port, the port was physically damaged. it was good at wiping/damaging? usb drives, if that's not your intended purpose, you probably should return it. |

Hmm Okay.
I'll return it and order another one.
Any suggestions on a good manufacturer which will work well under Linux?
Cheers!
