I need some help to find out why I am not getting the outcomes that I would expect.
The symptoms I am expecting are that the audio and the external USB are not working. I believe this has something to do with the USB Hub I am using. Although is getting powered up through a power strip (thanks @Lphillimore for this) it does not get recognised in lsusb command. When I execute the command it only shows 1 port detected but I would expected 4 or 5 ports to be detected. Since only one port is detected this might be the reason why the USB Sound Card is not detected either. Running cat /proc/asound/modules it only shows - 0 snd_bcm2835. At this point if the USB Hub was detected I would expect the 1 snd-usb-audio module to be shown as part of the command.
The issue I have just described above is the same as the one i had about a month ago. Originally I thought this was due to the fact that I was not using a power strip and that the USB Hub was not getting enough power. Now that I have added the power strip none of the issues seem to be resolved.
So, the output looks like the following:
The command below I don't know why is not recognising the sound card...

Thanks for going through the post. Any help is much appreciated!
in fact, ANY usb device runs like a dream on this chip on 2.0
