TMDSEMU110-U: Device not responding

Part Number: TMDSEMU110-U

Hi,

I received a brand new XDS110 debug probe few days ago.

However, it's not responding when connected to the PC.

The PC does not recognize any new device, and the indicator D1 on XDS110 does not turn on.

I have another working XDS110 in hand to be compared with, and have already cross examine the connection cable between XDS and the PC.

Please help.

Thanks.

Hi,

Does it enumerate the Windows Device Manager? Does it report and unknown USB device?

Can you install latest FTDI driver?

Hi,

Nothing happens to the Windows Device Manager when it's plugged in.

No new COM port and no unknown USB device.

I've also tried Scan for hardware changes, and there's still nothing new.

I install the drivers you mentioned and it's still the same.

Thanks

Hi,

Can you try the USB cable from working XDS110, just to isolate it is not the faulty USB cable?

Thanks & Regards,

I have tried multiple cables,

and have been using the cable from the working XDS110 since your first reply.

I also cross examine the working XDS110 in these tests, and that one works every time.

Thanks

Hi,

Thanks for trying these things - just wanted to make sure it is really the emulator or issue in USB cable, FTDI Windows Driver or other stuff.
