Such a problem: Tablet 4.1.1 JellyBean. There is a USB otg, the keyboard and mouse are separately connected, but at the same time there is no hub. When I do lsusb the device says that there is a hub, but the mouse and keyboard connected to the hub do not work. Can anyone come across this. Also inside is Debian, it can somehow connect through it.

- Your hub does not put on vbus. There may be several reasons, starting with the banal absence of an external power source. - 0andriy
- I checked the voltage, in the first case without a hub 5.3 volts, and with a hub 5 volts. 5 volt mouse, but does not work. Could this be due to a 0.3 volt difference? - Allespro
- See, VBUS should be checked on ports external to the hub, the hub cable itself should nullify the ID contact. - 0andriy
