USB and LAN ports not working

Former Member

I received my Raspberry Pi today, but unfortunately neither the USB ports or the LAN port appear to be working.

 

I have tried numerous low power USB devices like keyboards mice etc. but can't get any life out of them, although I am able to charge my phone from the ports. Same results using two different 2A adapters to power the Pi and with a powered USB hub.Tried connecting the LAN port but the light on the router indicating a device is attached did not come on.

 

I've tried Debian, Arch and Fedora from RaspberrPi.org and also tried the kernel update which I believe is to address a different issue with USB. At this stage I'm fairly sure there is a fault (LAN is connected through USB I believe?). I'll wait and see if anyone else reports similar problems, otherwise I think I'll have to return it.

 

Does anyone have any suggestions or has had a similar experience with theirs?

 

Thanks

  • There are issues with many powered hubs interfering with the eth0 hardware in the current Debian and Arch kernels.

     

    These issues will probably be resolved in later kernel updates, but in the mean time, I recommend not using a hub and plug the bare minimum of USB devices into the Pi.

     

    Just a keyboard and an ethernet connection would be a good starting point.

     

    Do you get any error messages when booting up? Post a dump of your dmesg output and someone might be able to help.

     

    Log in and then type

     

       dmesg > output.txt

     

    for a full dump or filter it with

     

       dmesg | grep eth0 > output.txt

     

    Also, do you have dhcp enabled on your router?
