I have a USB peripheral (IO module) in my system which is not responsive upon boot fairly often. Some of the time reenumeration (unbind / bind) will resolve this, but not always. I would like to be able to cycle the USB power to the device to attempt recovery. On the IGEPv2 schematic it looks like the nEN_USB_PWR signal from the TWL4030 will do this, so I have been trying unsuccessfully to access the TWL4030 via I2C1. The I2C driver is telling me the device is busy when I try to set the slave address. Is it possible for me to access the TWL register set at runtime? Or is there a better way to cycle power to the USB Host Connector?
