But, if I run 'ip a' I do not see other new network device (ethX).
It's possible resolve this issue and use this USB network device?
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!
