USB Hub and Ubuntu












1















I have a powered 7 port hub connected to my Ubuntu box and it does nothing.
The devices (zip drive and web cam) work direct, but aren't recognized through the hub.



This worked fine in Windows 7. I can't prove it is the OS because this is a new motherboard and processor.



Any advice?

This is with the powered hub plugged in.

    This is with the powered hub plugged in.

      I have a powered 7 port hub connected to my Ubuntu box and it does nothing.
      The devices (zip drive and web cam) work direct, but aren't recognized through the hub.



      This worked fine in Windows 7. I can't prove it is the OS because this is a new motherboard and processor.



      Any advice?

      This is with the powered hub plugged in.










      share|improve this question
















      I have a powered 7 port hub connected to my Ubuntu box and it does nothing.
      The devices (zip drive and web cam) work direct, but aren't recognized through the hub.



      This worked fine in Windows 7. I can't prove it is the OS because this is a new motherboard and processor.



      Any advice?

          lsusb - list USB devices



          To make use of all the features of this program, you need to have a Linux kernel which supports the /proc/bus/usb interface (e.g., Linux kernel 2.3.15 or newer).



          sudo lsusb
