Hello, i'm currently working on a project that uses the USB Host and Ethernet functionality on the Teensy 4.1 to inject / modify mouse input. I've attached an example with the whole ethernet side removed and just acting as a forwarder.
During my testing I've noticed that using my mouse with report rates above 1000hz produced noticeable stutter movements that look like jumps (missed polls?) semi-consistently.
I've modified the descriptors of the Teensy to be a 1:1 match of the mouse and can see a max polling rate of about ~1850hz when set to 2000hz on the mouse, which is pretty inline with what i see on a direct connection to my computer. When the sutters occur there is a drop in reported polling rate of about -500 which then shoots back up shortly after.
Tested on multiple USB ports on my computer, making sure to test CPU and Chipset ports for different behavior. This is also replicated when using my laptop. This behavior also stops happening when using the exact same mouse set to a lower report rate such as 1000hz or 500hz.
Mouse used: Attack Shark R5 Ultra set to 2000hz.
