Hello there! I'm created basic workaround for this by creating little daemon which rescan usb bus every one second. I know it's hack, but as temp solution is ok.
Source file: usb_fix.c <http://sdelab.ru/usb_fix.c> Compiled binary on BBB ubuntu 13.10: usb_fix <http://sdelab.ru/usb_fix> You can add copy binary to /bin directory and add to rc.local /bin/usb_fix to force start daemon on system start. I hope this helps! среда, 22 мая 2013 г., 9:22:47 UTC+4 пользователь Edouard Lafargue написал: > > On my new BBB, I have noticed that if I power it up with a USB peripheral > connected to the host port, that peripheral works fine.
