Sorry , we do not have other chips and do not know if their same ip is actually the same. You can use v307.

Same log with data MCU sent to host.

Only support CH32V307, although their ip is the same ,but is not the same too, thanks.

I also have ch32v305 chip, I replace it on the board and try it. I don't believe, I want see myself.

Same with 305 chip. This is really strange. Later I will get usb analyzer and can inspect what is really going on the bus. Now seems I cannot use cherryusb :-(

Can I donate you some hardware, so you can try run your project on it?

Please turn off the log or lower the log level before testing.

I will wait until USB analyzer will come to me (maybe several weeks later) and continue testing with it. For sure will try with and without log. Thanks for advice, yes I know that log can affect timing, moreover I am using 115200 uart log, that is not very fast.

Finally I choosed tinyusb stack (https://github.com/hathach/tinyusb) instead of cherry (sorry).
I managed ch32v307 usbfs and ch32v103 usbhd work on it. There is usbd controller that I also want bring up. With these four drivers all ch32 usb peripherals should work. maybe later will make PR to tinyusb, Follow up if you interested.
