[CentOS] USB to Ethernet problem

Hello All,

?I installed Centos 6.5 64 bit on a Dell Vostro 1550 laptop with i3 core. The
kernel installed was 2.6.32-431.el6.x86_64. I was not able to compile kernel
modules, even after installing the kernel headers, kernel source rpms.

?So I downloaded the kernel linux-3.10.31.tar.xz, extracted it, and did the
following:

make defconfig

change CONFIG_USB_USBNET=y, in the .config.

make

? ASIX AX88xxx Based USB 2.0 Ethernet Adapters (USB_NET_AX8817X) [Y/n/m/?] (NEW)
n
? ASIX AX88179/178A USB 3.0/2.0 to Gigabit Ethernet (USB_NET_AX88179_178A)
[Y/n/m/?] (NEW) n

????? All the other options selected the default.

make modules

make modules_install

make install

Then I booted from 3.10 kernel, which went thru fine. After logging in into the
3.10 kernel, I compiled and insmod the asix driver for usb to ethernet. Upon
insmod, the eth1 interface comes up, but with no IPV4 address assigned. So I
assigned a static IP address using ifconfig. Then added a route for the default
gateway.

Now, after assigning a static IPV4 address, this eth1 is pinging to the default
gateway 192.168.1.1. But eth1 is not pinging/connecting to the external
internet. Can someone please provide some answers.

?I am using the device from www.svbinternational.com. The device is labeled USB
2.0 to network 10/100Mbps ethernet adapter. Device id, as can be seen from lsusb
is: Device 003: ID 0b95:772b ASIX Electronics Corp. AX88772B.

Thanks in advance.

Regards,
Giri

The same device on Windows 7 64 bit, same laptop, gets the IP Address and mask
as 169.254.74.198, whereas the wireless interface is properly assigned the IPV4
address as 192.168.1.2 :

If you can, then most likely a DNS config issue!  Since you mention you 
had to assign an IP Address manually, the file /etc/resolv.conf may not 
have the necessary DNS info to resolve Internet names!

I backported this driver for el6 at elrepo. Rather than compile and 
maintain a complete kernel from source, you could have just set up 
elrepo and done 'yum install kmod-asix'.
