We are facing some problems when we "hotplug" USB devices on the JumpStart kit for the ConnectCard Wi-i.MX28. When one USB device is connected at startup, everything works great : The USB device is correctly detected by the iMX28.
The problem appears if we plug the USB device when the iMX28 is already started. In this case, an IRQ error appears :
irq 93: nobody cared (try booting with the "irqpoll" option)
Disabling IRQ #93
And the device is not recognized by the iMX28.
How can we solve this problem ?
