Hi,

 

I am using SAMD21G18A and wonder why DSU.STATUSB.HPE (Hot-Plugging enable) is always 0 despite the reset value should be 1. I don't have the Security Bit set which is according to the manual the only reason whch could disbale the HPE after boot. What do I miss?

 

Any comments are welcome

 

regards
