Hi, I am working on a new UDC for a new USB chip. The kernel version is 3.4.4. When I insmod the new UDC, it is ok. When I insmod the file storage gadget , error occurred "No such device". # ls g_file_storage.ko g_mass_storage.ko kagen2_udc.ko # insmod kagen2_udc.ko # insmod g_file_storage.ko file=/dev/mmcblk0 insmod: can't insert 'g_file_storage.ko': No such device # insmod g_file_storage.ko file=/dev/mmcblk0p1 insmod: can't insert 'g_file_storage.ko': No such device do I insmod the file storage gadget separately? The /dev/mmcblk0 refers to SD card, right? I insmod the sd card driver already. # lsmod kagen2_udc 7262 0 - Live 0xbf02f000 ka2000_sdio 6643 0 - Live 0xbf005000 ka2000_sdhc 5291 0 - Live 0xbf000000 thanks, Victor ================================================ CONFIDENTIALITY NOTE: This e-mail and any attachments may contain confidential information and may be protected by legal privilege.
