The hub itself disconnects the device electronically, the kernel does not do that. When the device comes back, then it is initialized by the kernel, as the logs show, but then it is disconnected again. This really looks like broken hardware or electronic noise on the connection, the kernel can not cause electronic disconnects on a USB hub like this. good luck! greg k-h _______________________________________________ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org https://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
