SPC582B-DIS Hardware Problem (USB)
Hello, we bought 3x SPC 582B-DIS Eval Boards. I tested the first one with one of the examples provided in the SPC5 Studio successfully ~2 months ago. Last week I tried to put it into operation again but in Windows it's not recognized ("unknown usb device (port reset failed)").
I thought that this might have been due to ESD issues or mechanical stress during storage, so I tried the second Eval Board which was working perfectly at the beginning. This time I was more careful (Operation and storage only in air-conditioned ESD lab).
Nevertheless, the Board worked less and less over time while testing several examples (always lost USB connection during operation - needed to reconnect USB). Now the board is in the same state (not being recognized by Windows), no matter how often I plug it in and out.
Especially for the second board I took care that no mechanical or electrical stress (not even electrical measurements) were applied.
In the device manager, it's displayed as "unknown usb device (device descriptor request failed code 43)"
I tested
- the USB voltage on the board, it's always at 5V, nothing unusual here
- a different computer (different model) -> same behavior
- Powered USB Hub/all USB Ports -> same behavior
Is this a known problem? I'm fearing that a PLS UDESTK Debugger will behave similar.
Thank you for any help!
I'm going to test my third (and last) board now...
