Title: fusb302 4-0022: connection has disconnected [Print This Page] Author: acidpero Time: 12/18/2018 09:23 Title: fusb302 4-0022: connection has disconnected There is no problem to using board
However, I wanna know why the 'USB Type-C' is on the board and why the error like the title occurs.
I wonder why this is happening.
please let me know.Author: penguin Time: 12/20/2018 14:56
Hi, @acidpero, how did you get that message?
After booting up, I only get this:
$ dmesg |grep fusb302

------------------------------------
when boot without connecting the USB Type-C port to the Host PC, I got the same message like yours.
But when I boot them with both connected, I got the following message.
# Kernel Log, filtered (fusb302)

I would like to know why there is a USB Type-C port other than flashing. Author: penguin Time: 12/22/2018 17:35
The board can be served as USB widget, where the Type-C port will be in device mode.
But by default, both the board and PC are in host mode, which makes no sense when
connected together, therefore the fusb302 chip reports ROLE_MODE_NONE .Author: luokuipeng Time: 7/4/2019 20:46

我的也这样，不知道啥问题Author: jh244212647 Time: 1/4/2020 15:36
because firefly_rk3399 use the type-c by otg mode,but there is different both otg wire and defualt wire. so if you want to use the default wire,you can chang the otg mode ,modify dts,chang the &&usbdrd3_0 to &u2phy0
