Thanks to Heiner Kallweit <\/strong>for info on two USB patches for the Odroid C2, and thanks to John Youn<\/strong> for the patches themselves..\u00a0 They can be found at http:\/\/www.spinics.net\/lists\/linux-usb\/msg151687.html<\/a> and http:\/\/www.spinics.net\/lists\/linux-usb\/msg151688.html<\/a> .<\/p>\n

I have applied these to Kernel 4.10-rc4<\/strong> (including the Ethernet TX patch) and now USB is working, and detects\/connects devices – sort of..<\/p>\n

Plug in USB device, does not show up (same behaviour as before patch):<\/p>\n

]# lsusb<\/span><\/strong>\r\nBus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub<\/span><\/strong>\r\nBus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub<\/span><\/strong><\/pre>\n
But, do (as root)<\/p>\n
# lsusb -v<\/span><\/strong><\/pre>\n
then<\/p>\n
# lsusb<\/span><\/strong>\r\nBus 001 Device 006: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter<\/span><\/strong>\r\nBus 001 Device 002: ID 05e3:0610 Genesys Logic, Inc. 4-port hub<\/span><\/strong>\r\nBus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub<\/span><\/strong><\/pre>\n
Remove:<\/p>\n
# usb 1-1.1: USB disconnect, device number 6<\/strong><\/span><\/pre>\n
More than one device:<\/p>\n
# lsusb<\/span><\/strong>\r\nBus 001 Device 008: ID 0d8c:000c C-Media Electronics, Inc.

USB ‘disk’:<\/p>\n

So..\u00a0 There is more testing to be done, but at least some more core functionality is available..\u00a0\u00a0\u00a0 I also need to check the kernel config, to see if there is another option to be included, to make ‘detection’ work correctly..<\/p>\n
As usual, it remains to be seen whether these particular USB patches make it into the mainline<\/span> kernel tree..<\/p>\n
