No, it's not possible - I've made it this way to make things simpler for
users.
To disable it - remove lines
if (hid_enabled)
android_enable_function(dev, conf, "hid");
from
https://github.com/pelya/android-keyboard-gadget/blob/master/kernel-3.4.patch#L119
Then you will have to execute this command to enable HID, from the root
shell:
echo 0 > /sys/class/android_usb/android0/enable
echo mtp,adb,hid > /sys/class/android_usb/android0/functions
echo 1 > /sys/class/android_usb/android0/enable

It think it should be possible to activate/deactivate it like mtp,

Hi,
I applied the patch for kernel 3.4. Now I found directory "/sys/class/android_usb/android0/f_hid" in my phone, but NO "/dev/hidg0" or "/dev/hidg1".
$ cat /sys/class/android_usb/android0/functions
mpt,adb

If you modified the patch, you need to enable HID mode by hand. Until then,
there will be no /dev/hidg0 and hidg1.
Execute following commands in the root shell:
echo 0 > /sys/class/android_usb/android0/enable
echo mtp,adb,hid > /sys/class/android_usb/android0/functions
echo 1 > /sys/class/android_usb/android0/enable
You habe to do that each time you plug a cable to USB post, because Android
system will override HID mode with just 'mtp,adb'.

Hi Pelya,
Yes, the patch is using the "hid_enabled" check.
See code here: Al3XKOoL/tinno82_S5501@d6ff89b#diff-d3d3db76db0b001fddee1bdcfc972c17R1855
But when I execute this script as root:
#!/system/bin/sh
echo 0 > /sys/class/android_usb/android0/enable
echo mtp,adb,hid > /sys/class/android_usb/android0/functions
echo 1 > /sys/class/android_usb/android0/enable
Then the ADB disconnects, no MPT, and no HID devices.
When I unplug and I replug device, then Windows identifies it as "Unknown Device". No hardware ID.
But, If I change from MTP to PTP, then this restores the USB functions.
Where you think is the trouble?

@lars18th replace lines
if (hid_enabled)
android_enable_function(dev, "hid");
with just
android_enable_function(dev, "hid");
Then it will always be enabled. I've removed that 'hid_enabled' check some time ago from all my patches, but the old version of the patch still flies around the net.

Hi Pelya,
With current version of the kernel (without the line "if (hid_enabled)") the HID-Gadget patch is working: I can send keystrokes using the tool hid-gadget-test.
However, I have found a problem with the current patch. I comment the problem:
- By default, the USB mode in my Android device (with the patch applied) is: mpt,adb,hid. Because I need to connect the Android device to a very buggy USB device, I like to enable ONLY keyboard and mouse emulation over the USB connection. Then I execute these commands from the shell (as root):
$ echo 0 > /sys/class/android_usb/android0/enable
$ echo hid > /sys/class/android_usb/android0/functions
$ echo 1 > /sys/class/android_usb/android0/enable
And when I execute the last line the Android device freezes. Only with a hard-reboot (remove battery) I can restore it.
You know where is the problem?
Thank you for your time!

No, I never tried to use it this way. Looks like you'll need to add
printk() to each function, and trace where it freezes. Or you can try to
debug it -

Maybe you are initializing HID module twice? There is already one explicit
initialization inside enable_functions(), and when you do
echo hid > /sys/class/android_usb/android0/functions
there is another initialization.

Hi Pelya,
After weeks using a kernel with your patch applied, I found that in some cases the kernel hangs when changing the USB mode. I suggest that you reimplement a safe mode for enable/disable HID mode. Perhaps this can be complex, but it minimizes the cases of a crash.
Regards!
from android-keyboard-gadget.
Answer has been given: to deactivate HID;
- compile with android_enable_function() commented out
- Execute in root shell (replace $FUNCTION with what you would like to have):
echo 0 > /sys/class/android_usb/android0/enable
echo $FUNCTION > /sys/class/android_usb/android0/functions
echo 1 > /sys/class/android_usb/android0/enable
Possible functions are adb, mtp, midi, ptp, charging, ffs, hid; seperated with a comma (,) and no whitespace.
