UE200 USB to Ethernet Adapter not initializing in boot about firmware

Update: I tried connecting with Jetson AGX and it is initializing with tegra-xusb

Does this mean xhci_hcd is not supporting the Ethernet module?

No, I don't think that's the case.

if unplug and plug it it works fine

That sounds like some sort of power-on glitch - it could be due to timing of reset signals, or perhaps the system is running out of power.

• Which power supply and cable are you using?
• Do any of those devices have independent power supplies, or is the Pi supply having to power them all?

Hi @pelwell,

I'm using the official rasberry pi adapter with rating 5.1V, 3A Link.

I had the same doubt regrading the power issues so i disconnected all the other connection from rasberry pi but that didn't solve the problem.

Do you have a USB hub? If so, try putting it between the LAN adaptor and the Pi 4 - sometimes that can help with devices that are not particularly standards-compliant, and it would be interesting to know if this issue might belong to that class of problems.

Sure i'll try with USB hub and let you know the results

Hello @pelwell,

I tried with this USB hub without and with external power of 5V/3A still the issue persists.
