Hi, I'm using USBProxy with NanoPi Neo and Epic430 printer, it's working as expected with Linux and some Windows hosts but not working with specific Windows host.

Running under kernel 5.3.0-rc7

Then host reports error. I also grabbed tcpdump from NanoPi https://imgur.com/a/ARsMJGZ Can anyone explain why host could reject device?

Hi @Leon90PL, did you try out the changes in the mweal-ed fork? We merged them in dev today and it fixed many issues (e.g. graceful exit, hotplugging, memory leaks). Could you please confirm your issue persists with the dev version? Which OS are you running on your NanoPi?

Leon90PL commented 3 years ago

Hi I tried with dev branch but I guess there is a problem with disconnection. Im using Armbian

I also noticed when host sends SET_CONFIGURATION, there is an error on reading from FD void HostProxy_GadgetFS::control_ack() read(p_device_file,0,0);

Hey @Leon90PL, I am sorry that I cannot help you with this one atm. We support the rpi 4b only at Nesto and I lack the required low-level C skills to guess the root cause of your issue without having such a device. I hope to get some people involved into this project who know that stuff!
