TOPIC: USBStreamer Kit Schematics

USBStreamer Kit Schematics 3 days 21 hours ago #42663

Hi,

For a prototype for a customer, I'm using the USBStreamer Kit.
While they were in a demo, the interface stopped working suddenly and the LED doesn't turn on anymore.

I've tested with one I have in-house, and apparently the LED turns on as soon as there is some power on VBUS, so I guess something really wrong happened.

We plan on using this interface for a big stage demo, I don't know exactly what went on, but I need to ensure that this doesn't happen on the big day.

For the post-mortem, I need to analyse the USBStreamer Kit, so I'd like to know if the schematics of the USB Streamer Kit would be accessible, or part of the schematics, with an NDA if required.

Thanks,

Raphael

@Raphael

unfortunately I'm afraid that we don't provide schematics for any of our products.. :-(
Are you maybe drawing some current from the interface? That could be an issue here..

Start simple, disconnect all external IO and proceed by elimination? Just a thought.

Hi,

Thanks for your reply.

The customer tested with the card in isolation and the led doesn't turn on, they tried on different computers, different USB ports, checked the ports were working with a mouse.

Can you please at least confirm that the path from VBUS to the led is quite direct, and doesn't go through the XMOS in some way?

Thanks,

Raphael
