Thank you Kevin for this detailed response! I have submitted an MFI DTS ticket now. It has the case ID: (Case-ID: 12584819) I am additionally going to file a bug as you suggested as well and am just gathering all the needed information for that (mainly getting a good sysdiagnose log to include there). I will update here with the number for this issue once I have it submitted as well. As far as anything changing in terms of USB bus behavior, It should be untouched since the time of the initial accessory development so I suppose this leans more towards the bug potential. We have some further info after measuring the current flowing into the iOS device in both cases as well: Conditions: On Boot up PowerSourceUpdate msg sent by LPM to iPad -> AvailableCurrentForDevice = 0 mA iOS 17 Ipad Battery Level 31 PowerUpdate message parameters sent by iPad to LPM MaximumCurrentDrawnFromAccessory 0 DeviceBatteryWillChargeIfPowerIsPresent 0 IsExternalChargerConnected 0 BatteryChargingState 1 BatteryChargeLevel 30 Current measured at Connector 420 mA -> 0 mA iOS 18 Ipad Battery Level 46 PowerUpdate message parameters sent by iPad to LPM MaximumCurrentDrawnFromAccessory 0 DeviceBatteryWillChargeIfPowerIsPresent 0 IsExternalChargerConnected 0 BatteryChargingState 1 BatteryChargeLevel 45 Current measured at Connector 420 mA -> Persists at 420mA I'll be sure to include this above information in that new bug when it is written as well. Thank you, Nick

Hello again, I have filed a bug following that Bug Reporting best practices info. the bug number is FB16918962. I'll continue to assure we verify the USB portion on our side to assure further that nothing was missed there as well. Let me know if I can provide anything further to help the investigation. Best, Nick
