Linux laptop does not detect the board when plugged in via USB
#1
Hi there!
I was wondering if someone could help me try to figure out where to begin with troubleshooting this issue...
I have a Linux laptop that does not enumerate my rockpro64 when it is plugged in via the USB C port on the board.  Both the board and the laptop are running Gentoo.
I believe this is an issue on the laptop side, as I've had this problem with some other boards, an rpi zero and BBB, but I haven't had much luck figuring out the issue on the Gentoo forums.

Here's the kernel config for the laptop: https://dpaste.com/2HMMLKLYW
And for the board: https://dpaste.com/EQXMPZGRL

Here is the dmesg on the laptop:

Note that when the board is plugged in there's no feedback from dmesg whatsoever.  The laptop enumerates other USB devices (phone, storage devices) just fine.
I am not sure if this is a eudev or kernel config issue.  I thought that maybe this was caused by the board being in "host" mode rather than device, but I am unsure of where to go from here. 
Please let me know if there's any more information that would be helpful.

I have a Linux laptop that does not enumerate my rockpro64 when it is plugged in via the USB C port on the board.  Both the board and the laptop are running Gentoo.
I believe this is an issue on the laptop side, as I've had this problem with some other boards, an rpi zero and BBB, but I haven't had much luck figuring out the issue on the Gentoo forums.

Here's the kernel config for the laptop: https://dpaste.com/2HMMLKLYW
And for the board: https://dpaste.com/EQXMPZGRL
And my custom essay service

Here is the dmesg on the laptop:

Note that when the board is plugged in there's no feedback from dmesg whatsoever.  The laptop enumerates other USB devices (phone, storage devices) just fine.
I am not sure if this is a eudev or kernel config issue.  I thought that maybe this was caused by the board being in "host" mode rather than device, but I am unsure of where to go from here. 
Please let me know if there's any more information that would be helpful.

Sounds interesting. I wonder how this issue can be fixed. I will bump this thread so other people will see it.
