USB to Internet Adapter not recognized

[rin67630]

Cheers,

I tried to run a chineese no name USB-adapter with 3 USB ports and one RJ45 Network interface on a Raspberry pi Zero.


The USB-adapter with 3 USB ports and one RJ45 Network interface runs well on my Windows PC and the Network interface is detected as following: VID 0FE6 PID 9700

When I try to run it on a Raspberry pi Zero powered with a 5,3V, 3A Power supply I get the following errors on boot:

[ 297.500844] usb 1-1.3: device descriptor read/64, error -32
[ 319.010241] usb 1-1.3: device descriptor read/64, error -32
[ 319.230268] usb 1-1.3: device descriptor read/64, error -32
[ 319.550273] usb 1-1.3: device descriptor read/64, error -32
...

The USB is running well, but the RJ45 network interface does not work. Is is just not found in lsusb...

Has somone got a clue how to get it running?

The DM9601 Chipset Devices have proved problematic when used with Raspberry Pis, best to be avoided.

Your best option to make this adapter run is by shouting at the device and then flatten it with a hammer:
See https://elinux.org/RPi_USB_Ethernet_adapters under "Problem Ethernet adapters".

Dear Ernst,

you did not tell me to place the adapter on an amboss before flattening it with a hammer.
Nov my 2500$ Mac is ruined.

More seriously, which usb network+hub combi adapter would you recommend?

That one from your example list is exactly mine, which makes the described trouble:


P.S. I need a combo adapter, since I need to get a network connection and mouse+keyboard.
Speed is not an issue, it's only to initiate a VNC connection.

That's not the Freegene one - it's the black one to the right of the Smays device above the "ID's, Power & Drivers" table. (The photo's don't show both the USB ports)

Dear rin67630,

My mistake, I should have left out the shouting, the hammer is the better option

I looked at the VID 0FE6 PID 9700 and used that to find more information, however this was a mistake as I will show in a later post.
What I suggest is that you take a permanent marker to write the word "FAKE" on the adapter together with the MAC address, you might be able to get the MAC address with the use of a power supply like this https://www.raspberrypi.org/products/ra ... er-supply/.
Please wait with your reply until I have been able to write my next post on this.

Update: I wanted to post details about my findings with a similar fake hub/ethernet adapter but doing some research I found a thread that will give you all the information: viewtopic.php?t=225509

If you want to do some research yourself then you could use the following criteria "fake usb hub ethernet" , "dm9601 fake", "0fe6:9700", "1a40:0101", "00:e0:4c:53:44:58".

Let me supply additional information:

The network adapter works well and is reported on a Windows10 tablet as follows:
Manufacturer: Corechip Semiconductor, Inc.
Description: USB to Ethernet Adapter
Driver version: 1.0.906.0
Physical address (MAC): 00-06-08-0D-03-04

I tested it on my Android phone and it worked perfectly, I got my mouse working and ethernet oob.

In both cases it was run from the OTG power, without external power supply.

On (several different) Raspi Zeroes with a good power supply the bootlog reports:
$dmesg | grep error
[ 1.883031] usb 1-1.2: device descriptor read/64, error -32
[ 2.103074] usb 1-1.2: device descriptor read/64, error -32
[ 2.423069] usb 1-1.2: device descriptor read/64, error -32
[ 2.643016] usb 1-1.2: device descriptor read/64, error -32
[ 3.863045] usb 1-1.2: device not accepting address 5, error -32
[ 4.403075] usb 1-1.2: device not accepting address 6, error -32

So it fails to be recognised right at the kernel stage.

Indeed the Raspbian bug is dicussed here:
https://github.com/raspberrypi/linux/issues/2734
and here:
viewtopic.php?f=28&t=225509

My device is that one discussed (the cheaper version without the network isolator, but the Raspberries dont have one anyway).
Is it a fake?, probably. Albeit it works at least well on other host types like Windows and Android.
The main problem is that you never will know if you get a fake or not, when you purchase one.

I am designing concepts that can be used reliably by others, so this kind of devices will be a no-go.

Anyhow I just planned to use it transitorily to have a way adapting VNC on the local WiFi environment without a connected screen.

I have seen, that one may provide network and VNC connection with an Android Network sharing over USB as well, so I just lost interest to follow it further.

If by that you mean the isolating transformer that goes between the network chip and the socket, then all the "B" model Raspberrys do have them just they are built in to the socket instead of being a separate component.

Thank you for the info. One more thing that I learned today!
