Here I present the conversion of everything that is required to provide the equivalent of g_multi.ko with configfs. v1..v2: - removed the cause of Felipe returning -ENOLOG - moved fsg_common_set_sysfs invocation after the lun number is set, so that the latter operation does not try freeing nonexistent sysfs entries - adapted to earlier changes in multi.c (*_do_config) v2..v3: - rebased onto 3.12-rc1 v3..v4: - rebased onto Felipe's "testing" (3.12-rc3) A branch 'usb-gadget-configfs-3.12' is available at: git://git.linaro.org/people/mszyprowski/linux-srpol.git This series depends on a [PATCH v3] Equivalent of g_acm_ms with configfs, which has just been sent. BACKWARD COMPATIBILITY ====================== Please note that the old g_multi.ko is still available and works. USING THE NEW "GADGET" ====================== Please refer to this post: http://www.spinics.net/lists/linux-usb/msg76388.html for general information from Sebastian on how to use configfs-based gadgets (*). The g_multi.ko provides 4 functions: - acm (described in (*)) - ecm (http://www.spinics.net/lists/linux-usb/msg86561.html) - rndis (http://www.spinics.net/lists/linux-usb/msg86561.html) - mass storage (described in a series preceding the current one, I will reply to this post to send a link when spinics or gmane has indexed the series in question) and using all of them with configfs has already been described. The procedure of setting up a new "multi" gadget with configfs is given below with an example: $ modprobe libcomposite $ mount none cfg -t configfs $ mkdir cfg/usb_gadget/g1 $ cd cfg/usb_gadget/g1 $ echo 0x0106 > idProduct $ echo 0x04e8 > idVendor $ mkdir strings/0x409 $ echo my-serial-num > strings/0x409/serialnumber $ echo my-manufacturer > strings/0x409/manufacturer $ echo "Multi Gadget" > strings/0x409/product $ mkdir configs/c.1 $ echo 120 > configs/c.1/MaxPower $ mkdir configs/c.1/strings/0x409 $ echo "Conf 1" > configs/c.1/strings/0x409/configuration $ mkdir configs/c.2 $ echo 120 > configs/c.2/MaxPower $ mkdir configs/c.2/strings/0x409 $ echo "Conf 2" > configs/c.2/strings/0x409/configuration $ mkdir functions/mass_storage.0 $ echo /root/lun0.img > functions/mass_storage.0/lun.0/file $ mkdir functions/mass_storage.0/lun.1 $ echo /root/lun1.img > functions/mass_storage.0/lun.1/file $ mkdir functions/acm.0 $ mkdir functions/ecm.0 $ mkdir functions/rndis.0 $ ln -s functions/rndis.0 configs/c.1 $ ln -s functions/acm.0 configs/c.1 $ ln -s functions/mass_storage.0 configs/c.1 $ ln -s functions/ecm.0 configs/c.2 $ ln -s functions/acm.0 configs/c.2 $ ln -s functions/mass_storage.0 configs/c.2 After unbinding the gadget with echo "" > UDC the symbolic links in the configuration directory can be removed, the strings/* subdirectories in the configuration directory can be removed, the strings/* subdirectories at the gadget level can be removed and the configs/* subdirectories can be removed. The functions/* subdirectories can be removed. After that the gadget directory can be removed. After that the respective modules can be unloaded.
