QNX 6.6.0 SP1, x86 platform self hosted usb driver disables usb host's port
Randomly the usb hub port is disabled and the device (usb camera) is not accessible until the system is re-powered. The
only message in the system log is:
Jan 21 12:36:50 2 12 0 hub_transfer_done: hub (busno 1, devno 4, vid 0x0424, did 0x2517) - port 1 disabled
Jan 21 12:36:50 2 12 0 hub_transfer_done: hub (busno 1, devno 4, vid 0x0424, did 0x2517) - port 1 disabled
Jan 21 12:36:50 2 12 0 CLASS_PortDisabled: port 1
The usb server is started as:
io-usb -v -dehci -dxhci
The system usb configuration is attached.
Any idea or root cause why the driver is disabling the hub port ?
Regards,
Janusz
