DS416Play success with one remark!

[michelhandleitnl]

Great work, I used the Club USB-A 3.1 GEN 1 TO RJ45 2.5GB, and it worked instantly!
Only if i out a second Club adapter in the ds416play, the second usb adapter is not working.
The light blinks with interval of 30 secs, but isn't visible in /sys/class/net.
But still great work!

Dmesg output, the second Club 2.5 Gb nic gives the error (unregistered net_device): Get ether addr fail, there is no difference if I use a powered usb 3 hub.

This problem may be caused by a lack of power, but I'm not sure. This assumption may be confirmed by using a self-powered USB hub.

[michelhandleitnl]

Unfortunately I tried with a powered usb 3 hub, but the same issue occurs on a ds416play.

[bb-qq]

Have you tried the front port? Some users reported stability issues with the rear ports.

[michelhandleitnl]

I have tried all ports but the same issue stays.

[bb-qq]

I noticed that the device seemed to switch to USB-storage mode. I don't know that reason, but we may be able to switch its mode again to Ethernet using usb_modeswitch ([Related page|https://bbs.archlinux.org/viewtopic.php?id=228195])

Could you try this command?
usb_modeswitch -v 0bda -p 8152 -g 3-R
