Serial performance of USB devices?

[andyp1per]

I have it all working and have been able to connect to an STM32 based flight controller using usbipd on Windows 10 / WSL2. So first of all great job!

My question is how to make it go faster? The serial connection is very slow - much slower than a direct connection on windows using the same software and I am wondering if there are any settings I can change (e.g. via stty) to speed things up. I am connecting to /dev/ttyACM0

Thx - Andy

You may be suffering from issue #300. If you can, please follow the instructions in that thread to capture usbmon debugging traces. It may help solve the issue.

Hi here is the pcap file

Yep, this makes sense. The capture shows the same problematic behavior as #300. Glad it is fixed now. Thanks for the report!

Hey @dorssel your fix #307 cures this for me! Thanks!
