I'm currently facing one weird behaviour on my custom Linux and Windows driver.
The higher value of bInterval(for example, bInterval = 11/128ms/1024microframes is perfect) of the device's endpoint descriptor works perfectly for 2 bytes IN packets.
But if I choose lower value like 4/1ms/8microframes polling scheme interrupt IN packets on received at host side rather than continuous NAK packets sent by the device.
Interesting fact with bInterval = 4 case is that if I perform any activity over Bulk and Control endpoint than I can able to received interrupt IN packet perfect.
This is happened both in HighSpeed and SuperSpeed version of USB.
I Know about HighSpeed bus schedule each transaction in 1ms frame and start xfer data with the device. so this problem is related to USB scheduling at the host side.
My personal thought with bInterval is like if we perform higher polling frequency or lower bInterval value than t would be good to capture interrupt IN packet more accurately without much latency.
