问题 I have a USB RFID device that appears on /dev/hidraw for my serial devices they appear on /dev/ttyUSB* i used pyserial and it works like charm but for this one i couldn't read from it using cat /dev/hidraw0 need root privileges plus i need to read one line and not keep on listening I used evdev library but my device doesn't appear at all : import evdev devices = [evdev.InputDevice(fn) for fn in evdev.list_devices()] for device in devices: print(device.fn, device.name, device.phys) So is there

问题 I'm trying to connect my Raspberry PI to Pic4550 via USB. (Pic function is ok with windows c# program!). So I have installed rpi 2, pyusb, and tried to communicate with the help of [https://github.com/walac/pyusb/blob/master/docs/tutorial.rst][1] I get connected to the USB device, lsusb shows: Bus 001 Device 006: ID 04d8:0080 Microchip Technology, Inc.

It seems raspbian does not support HID over Gatt, which means that I need to implement/mimic a minimal HID over GATT behaviour using python. (Please correct me if there is a more straight-forward way to do
