Strykar Posted March 15, 2019 Share Posted March 15, 2019 I have a 4-port USB 2.0 hub powered by a 5V 3.1A power supply that does not show up on my C2, with or without devices connected to it. I have the C2's USB OTG port disabled as I use a DC power supply. $ sudo lsusb Bus 001 Device 004: ID 1df7:3010 Bus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub dmesg does not log the hub connecting/disconnecting. How do I troubleshoot this? armbianmonitor -u: http://ix.io/1DzS Link to comment Share on other sites More sharing options...
TonyMac32 Posted March 15, 2019 Share Posted March 15, 2019 Do you have anything plugged into the hub when you boot the board? This may be related to the other issue concerning partial power-down. Link to comment Share on other sites More sharing options...
Strykar Posted March 15, 2019 Author Share Posted March 15, 2019 As I mentioned earlier, I have tried booting with and without devices attached to the hub, the issue persists. Link to comment Share on other sites More sharing options...
