Direzione di ricerca
Start by reproducing the failure with the Raspberry Pi Zero's dwc2 and libcomposite HID gadget setup, then inspect the kernel USB gadget and dwc2 remote-wakeup path involved in writes to /dev/hidg0. Done means a suspended host wakes when a HID key is sent and the write no longer fails with Resource temporarily unavailable.

Descrizione
Describe the bug
A raspberry pi Zero in HID gadget mode cannot wake host computer.
To reproduce
Enable dwc2 driver and reboot:
echo "dtoverlay=dwc2" | sudo tee -a /boot/config.txt
sudo shutdown -r now
Load modules:
sudo modprobe libcomposite dwc2
Add keyboard to ConfigFS:
#!/bin/bash
# this is a stripped down version of https://github.com/ckuethe/usbarmory/wiki/USB-Gadgets - I don't claim any rights
modprobe libcomposite
cd /sys/kernel/config/usb_gadget/
mkdir -p g1
cd g1

mkdir -p configs/c.$C/strings/0x409
echo "Config $C: ECM network" > configs/c.$C/strings/0x409/configuration
echo 250 > configs/c.$C/MaxPower
ln -s functions/hid.$N configs/c.$C/
ls /sys/class/udc > UDC
Now, output keys to /dev/hidg0
sudo su
echo -ne "\0\0\x4\0\0\0\0\0" > /dev/hidg0 #press the A-button
echo -ne "\0\0\0\0\0\0\0\0" > /dev/hidg0 #release all keys
When you are plugged in to a host computer that is on, it will output the keys. That works fine.
Next suspend the host computer, and try the same thing:
sudo su
echo -ne "\0\0\x4\0\0\0\0\0" > /dev/hidg0 #press the A-button
echo -ne "\0\0\0\0\0\0\0\0" > /dev/hidg0 #release all keys
You get an error:
bash: echo: write error: Resource temporarily unavailable
Per the kernel gadget documentation, this the remote wakeup functionality is supposed to be handled by the kernel gadget driver.
Expected behaviour
When you send keys to the host computer, the gadget driver should send the wakeup signal to the host computer, instead of just failing.
Actual behaviour
As mentioned previously, you can't write to the file
