I currently have a very weird problem. Maybe someone can help me. We are using a Mini64110 with Android and connect a IOIO board to it (http://www.sparkfun.com/products/10748). The first time I connect it, everything works (even though there is that connect-debounce error) and I get the following log on the console (via serial port): / # s3c-hsotg s3c-hsotg: new device is full-speed s3c-hsotg s3c-hsotg: S3C_GINTSTS_USBSusp usb 1-2: new full speed USB device using s3c2410-ohci and address 2 s3c-hsotg s3c-hsotg: s3c_hsotg_irq: USBRst hub 1-0:1.0: unable to enumerate USB device on port 2 s3c-hsotg s3c-hsotg: new device is full-speed s3c-hsotg s3c-hsotg: new address 1 android_usb gadget: full speed config #1: android hub 1-0:1.0: connect-debounce failed, port 2 disabled hub 1-0:1.0: connect-debounce failed, port 2 disabled hub 1-0:1.0: connect-debounce failed, port 2 disabled hub 1-0:1.0: connect-debounce failed, port 2 disabled When I then disconnect the IOIO I get s3c-hsotg s3c-hsotg: S3C_GINTSTS_USBSusp usb 1-2: new full speed USB device using s3c2410-ohci and address 3 usb 1-2: device descriptor read/64, error -62 usb 1-2: device descriptor read/64, error -62 s3c-hsotg s3c-hsotg: OTGInt: 00000004 s3c-hsotg s3c-hsotg: s3c_hsotg_irq: USBRst hub 1-0:1.0: unable to enumerate USB device on port 2 and finally when I try to reconnect it, it doesn’t work anymore.

It works fine with other ARM boards running Android.
