Hello, I stumbled on a problem that I need some suggestion to continue tracking where the problem is. I started a tip session to the usb port, after typing two characters, any more input returned TS_BUSY. I noticed that this problem also exists when I do a 'cat junk > /dev/ucom0'. After two consecutive usbd_transfer(), it sits there.
After some code tracking, I found that the ucomwritecb() for the third usbd_transfer() never gets called in uhci_idone(). I haven't dig further down yet. I'm going to do that tomorrow. If you have some idea, or have some suggestion how I can tackle this problem, please shine some light on me. The first two usbd_transfer are successful, and I could see the packets going out to the USB port with a USB analyzer. Thank you so much.
