Davicom 9601 USB to Ethernet convertor issue with Beagle Board RevC4

Hi,

I am trying to use Davicom 9601 USB to Ethernet convertor with my RevC4 Beagle Board, Kernel: Linux 2.6.29,  from Bitbake package.

When I plug in the adapter, instead of eth0:register 'dm9601' mesage through dmesg, I am seeing the following on Beagle Board:

##################################################################################################

I have enabled support for Davicom in the kernel config(PHY) and in Network Adapters, even then I face this issue.  One more observation I have made is that the USB device also fails to get detected after connecting the Davicom 9601. If this is a known issue please let me know. This is very critical for me, please provide suggestions as to how to get it working with the Beagle Board, Also,  is  there any recommended USB to Ethernet convertor???  Awaiting a response .

    Ajit,

    Is your device a full speed device (USB1.1)? If so then you need to connect to beagle port through a hub. Can you try connecting a high speed (USB2.0) pen drive and see if it works.

    Hi Ajay,

     

    Thanks for your prompt reply, My pen drive is detected by the board without any issue. But just after I connect the Davicom 9601 and then try to connect the USB , the USB is not detected.

    How do I get to know if my Davicom is full speed ( I am using it for first time). 

    Though when I connect this device in X86 platform, kernel: 2.6.29.4-167.fc11, in the dmesg I see 

    ########################################################################

    usb 2-1: new full speed USB device using uhci_hcd and address.....

    ##########################################################

     

    Is that what you are pointing to??

     

    Log for high speed USB device getting detected:

    Ajit,

    the devcie is a full speed device so you need to use a hub to connect it.

    "usb 2-1: new full speed USB device using uhci_hcd and address....."

    Hi Ajay,

     

    Thanks a lot, Can you provide me any specific vendor other than Davicom where I dont need to use a USB hub? I do not have a USB hub inhouse.

     

    Thanks & Regards,

    Ajit
