Hi folks, Here is our bug tracker, https://blackfin.uclinux.org/gf/project/uclinux-dist/tracker/?action=TrackerItemEdit&tracker_id=141&tracker_item_id=3788 ZiO! CF card reader is here: http://www.psism.com/zio.htm - Firstly, MUSB is working as in host mode which can be figured out by the debug message. - Enumeration of the ZiO! CF card reader is OK. - When the upper drivers/usb/storage/shuttle_usbat.c try to send out the first packet: -- /* Enable peripheral control signals */ rc = usbat_write_user_io(us, USBAT_UIO_OE1 | USBAT_UIO_OE0, USBAT_UIO_EPAD | USBAT_UIO_1); if (rc != USB_STOR_XFER_GOOD) return USB_STOR_TRANSPORT_ERROR; -- - Finally, we got VBUS_ERROR interrupt in peripheral mode. I don't know how to recover it. If I am not wrong, the ZiO! CF card reader must have dropped the VBUS and this triggered the mode change of MUSB. Are you guys have any idea about this? B.T.W, I found the packet sequence of drivers/usb/storage/shuttle_usbat.c is not the same as Windows Host does. So I modified the code to send out the same packet as Windows Host. The result is the same.
