Hi Mattijs, The case was reported in early May and MCHP have also observed the missing of detach event on host. My latest measure shows a differential signal level about +-350mV between DP&DM lines when DETACH and PULLD_DIS bits are 1, much lower than the detachment threshold of 625mV from USB 2.0 specification Table 7.3. >From my view the patch can be picked, even on an unaffected family it won't have side effects. Unless one day we decide to implement SAM9RL and SAM9G45 errata then it needs to be retested. Best Regards, Zixun
