HLF1081A USB-OTG to LAN

[dolphs]

Hi - Trying to find out if a "HLF1081A NO:9700" Micro USB 2.0 to Ethernet 10/100 RJ45 Network LAN Adapter will work on Raspbian. Currently I do not owe a PiZERO therefore like to find out if one uses this adapter succesfully and moreover which kernel driver is being used, ( r8152 ) ? Cheers

Confused by post title, what has USB-OTG got to do with using a USB to RJ45 Adaptor ?


It would appear that the USB-RJ45 Adaptor uses a Asix Chipset which is supported in a fully updated Raspbian Jessie.

Hi - Thanks for your reply . Please note this one has a Micro USB 2.0 to Ethernet RJ45 Network LAN Adapter which I like to connect directly ( thus without USB to micro-USB converter ) to my PiZERO. Anyway ASIX should be good too! thanks again

looks like the USB dongle gets identified as " ID 0fe6:9700 Kontron (Industrial Computer Source / ICS Advent) DM9601 Fast Ethernet Adapter " on my Linux Distro ( Mint 18.1 ) - will find out shortly if it will be detected on my RPi ( with Raspbian ) and if it does, will it be stable for VPN ( referring to buggy drivers/ etc ).

The DM9601 is fully supported now and some bugs have been ironed out. It still has a USB1 interface though and can't cope with data much over 10Mb/s

[dolphs]

hmm where is that documented it has a USB1 interface as it is sold as USB2?
Or you mean the Linux driver has only support for 10Mbit ?
Anyway plugged it in to the PiZero and following can be seen, modules sr9700 and dm9601 loaded :

Hi,

Coming back to

The DM9601 is fully supported now and some bugs have been ironed out. It still has a USB1 interface though and can't cope with data much over 10Mb/s

Is this for all USB OTG devices on the RPiZ as I quickly tested a Realtek 8152 device, but iperf did not show more than 12,5M/bit which is close to USB1.1 speed. Hopefully this can be tuned close to 100M/bit

No, just the DM9601.
The RTL8152 is a full USB2.0 device supporting 480Mb/s. The ARM in the Pi zero isn't powerful enough to maintain full USB2.0 rates, but it should be able to go a bit faster than 12.5Mb/s (which is about twice what I'd expect from a USB1.1 device).

[dolphs]

that is a pity, though 25Mbit should be fine in my case.

Therefore I tested a 2nd vpn, which is identical configured as the RPiZ but running on a RPi2.
That shows indeed the results as expected ( note my upload speed is max 27.0Mbit/s ):

The other way round measured is roughly 30Mbit ( while 100Mbit/s ) is the maximum:

iperf -s ( to 192.168.10.57 with settings -t30 -P1 )

If similar could be achieved with the RPiZ ( r8152 ) that would be great.

[dolphs]

indeed omitting the VPN things look quite different I can confirm rt8152 is 100M/bit.
Did a quick test between RpiZ and RPi2

and to be on topic again ...
Please dont buy this HLF1081A adapter if you expect 100Mbit speeds it will disappoint you greatly.

Actually this one does work, see: https://www.jeffgeerling.com/blogs/jeff ... networking


Realtek Chipsets RTL8152 USB2 & RTL8153 USB3 they work good.


If you can buy from Google this is a neat PSU / Ethernet: https://store.google.com/product/ethern ... chromecast
