That sounds like quite a long time; can you remove a cap to shorten that?
Also - instead of removing the #define SELF_POWERED, you may want to replace it with
Code: Select all
#define SELF_POWERED 0
I beleive the larger issue is that it was a bus powered device that took a long time to power up. Therefore the xmos part had no power for a while (a bunch of milliseconds), yet a full 5V with no RC filter or anything to limit current. So... reality is probably 5V above VCC, plus whatever inductive kickback happened during plug insertion.dweeb4 wrote:What ripple & Freq was on the Vbus line that damaged the XMOS chip?
