203R series micro USB driver error

[ Edited ]

Dear community,

 

I'm trying to gain console access to a 203R RAP.

 

When I connect the RAP to my Windows 10 machine using a generic USB 2.0 A to micro USB cord I get an error: Unknown USB Device (Device Descriptor Request Failed). I never see the CP210x USB to UART device showing up in my device management.

 

I've tested 2 RAPs from the 203 series with same results, unfortunately I don't have any other type of AP with micro USB interface at my disposal. I've also tried various drivers with no success.

Anybody got any ideas to fix this issue? Do I need a special type of USB cable perhaps? 

 

Edit: tested a second RAP to see if the first one was faulty

Thanks for the quick reply, explains everything :-)

 

<edit> I'd like to express my frustration with Aruba's choices regarding console access. I used to be able to trust on a serial port being available. I understand there is a need for ports with a smaller footprint but please, can Aruba make a decision and stick to it! I'm now adding a third console access cable to my inventory where I used to have just one. I'm almost counting on having to add a custom BLE interface in the near future to troubleshoot Aruba products.

Hey Victor,

 

The custom USB cable arrived, unfortunately I'm getting the exact same error: Unknown USB Device (Device Descriptor Request Failed). 

 

Cable label says: AP-CBL-SERU,JY728A 3.3V TTL Serial Cable

 

I'm submitting a ticket for technical support, will update here in case we find a solution.

Re: 203R series micro USB driver error

How do I get these installed? I tried to manually update the driver by pointing towards the unzipped folder, but windows found no drivers inside.

 

I discovered today that a slightly newer laptop had no issues getting the USB cable to work on the 203R. It runs a newer version of Windows 10 (version 1703 creators update) compared to mine (Version 1607)
