You need to figure out what chipset your usb ethernet device uses. Maybe
it uses ax8817x driver like [0] says? Or D-Link decided to change the
chipset without changing the model number. ;)
Run lsusb and locate your device.
Use the "Bus" and "Device" numbers in the following command so you get more
info on just that device.
lsusb -v -s "Bus:Device" | egrep 'id(Vendor|Product)'
If you're lucky there will be some useful information in those two fields,
otherwise run the second command without piping it to egrep and read
through all the verbose info for clues.
It doesn't appear the ax8817x driver is shipped with stock CentOS 6 kernels
(and since 5 kernels are much older, don't expect it's 2.6.18.x kernel to
include the driver which came out around 2.6.21 or .23).
# find /lib/modules/2.6.32-358.23.2.el6.x86_64/ -iname 'ax88*' -print
And the word is that there's a bug or two [1] for the ax8817x drivers (this
Plugable device uses a similar chipset and it appears the same driver as
well) that aren't fixed until 3.2 series kernels. You may just have to
compile the module manually from source [2] which won't be horrible (since
these instructions are for Ubuntu you'll have to adapt them for RHEL/CentOS
as necessary).
** Don't hold me to any of this info until you know for sure which chipset
_you_ have!
