If you buy a *recent* USB to Ethernet adapter, embedding a Realtek chip, you
|
|
possibly face, like me, the following error, when connecting it:
|
|
|
|
```
|
|
r8152 4-1.1:1.0 (unnamed net_device) (uninitialized): Unknown version 0x6010
|
|
r8152 4-1.1:1.0 (unnamed net_device) (uninitialized): Unknown Device
|
|
```
|
|
|
|

|
|
|
This error is raised because your Linux r8152 driver is too old and doesn't
|
|
support your chip's variant.
|
|
|
|
In my case, I got the variant `0x6010` which has only been implemented in Linux
|
|
4.13, in the [commit
|
|
65b82d69...d3e7fb976](https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/usb/r8152.c?h=v4.13&id=65b82d696b9e84fda6dd7df61801b57d3e7fb976).
|
|
|
|
As I run at the time a 4.9 kernel and can't upgrade to a newer release, I
|
|
backport the commit to the 4.9 branch. You can find [the patch I made
|
|
here](r8152-for-4.9.patch). It only adds support for RTL8153B.
