I'm trying to read data from USB RFID reader using Python script. The data was write into a RFID sticker using NFC tool on my phone. So when I scan the RFID sticker at the RFID reader, Python script should display the data that I write into the RFID sticker. For example, I write a string into RFID sticker with "123456". I want it to display the string. I refer to this guide to read the RFID reader: https://github.com/charlysan/pyrfidhid But this does not work. I think it doesn't work because the script used for different reader model. I tried to find the RFID reader info on my Linux by using these command. sudo lsusb Bus 001 Device 004: ID ffff:0035 Sycreader USB HID READER sudo lsusb -vd ffff:0035 Bus 001 Device 003: ID ffff:0035 Sycreader USB HID READER Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 0 bDeviceSubClass 0 bDeviceProtocol 0 bMaxPacketSize0 64 idVendor 0xffff idProduct 0x0035 bcdDevice 1.10 iManufacturer 1 Sycreader iProduct 2 USB HID READER iSerial 3 20170320 bNumConfigurations 1 Configuration Descriptor: bLength 9 bDescriptorType 2 wTotalLength 0x001b bNumInterfaces 1 bConfigurationValue 1 iConfiguration 0 bmAttributes 0xa0 (Bus Powered) Remote Wakeup MaxPower 200mA Interface Descriptor: bLength 9 bDescriptorType 4 bInterfaceNumber 0 bAlternateSetting 0 bNumEndpoints 0 bInterfaceClass 3 Human Interface Device bInterfaceSubClass 0 bInterfaceProtocol 0 iInterface 4 USB VENDER HID HID Device Descriptor: bLength 9 bDescriptorType 33 bcdHID 1.10 bCountryCode 33 US bNumDescriptors 1 bDescriptorType 34 Report wDescriptorLength 38 Report Descriptor: (length is 38) Item(Global): Usage Page, data= [ 0xa0 0xff ] 65440 (null) Item(Local ): Usage, data= [ 0x01 ] 1 (null) Item(Main ): Collection, data= [ 0x01 ] 1 Application Item(Global): Report ID, data= [ 0x01 ] 1 Item(Local ): Usage, data= [ 0x03 ] 3 (null) Item(Global): Report Size, data= [ 0x08 ] 8 Item(Global): Report Count, data= [ 0xff ] 255 Item(Main ): Feature, data= [ 0x02 ] 2 Data Variable Absolute No_Wrap Linear Preferred_State No_Null_Position Non_Volatile Bitfield Item(Global): Report ID, data= [ 0x02 ] 2 Item(Local ): Usage, data= [ 0x03 ] 3 (null) Item(Global): Report Size, data= [ 0x08 ] 8 Item(Global): Report Count, data= [ 0xff ] 255 Item(Main ): Feature, data= [ 0x02 ] 2 Data Variable Absolute No_Wrap Linear Preferred_State No_Null_Position Non_Volatile Bitfield Item(Global): Report ID, data= [ 0x03 ] 3 Item(Local ): Usage, data= [ 0x03 ] 3 (null) Item(Global): Report Size, data= [ 0x08 ] 8 Item(Global): Report Count, data= [ 0xff ] 255 Item(Main ): Feature, data= [ 0x02 ] 2 Data Variable Absolute No_Wrap Linear Preferred_State No_Null_Position Non_Volatile Bitfield Item(Main ): End Collection, data=none can't get debug descriptor: Resource temporarily unavailable Device Status: 0x0000 (Bus Powered) sudo tree /dev/input /dev/input ├── by-id │ ├── usb-Logitech_USB_Optical_Mouse-event-mouse -> ../event7 │ ├── usb-Logitech_USB_Optical_Mouse-mouse -> ../mouse0 │ ├── usb-SONiX_USB_DEVICE-event-if01 -> ../event6 │ └── usb-SONiX_USB_DEVICE-event-kbd -> ../event2 ├── by-path │ ├── pci-0000:03:00.0-usb-0:7:1.0-event-mouse -> ../event7 │ ├── pci-0000:03:00.0-usb-0:7:1.0-mouse -> ../mouse0 │ ├── pci-0000:27:00.3-usb-0:4:1.0-event-kbd -> ../event2 │ └── pci-0000:27:00.3-usb-0:4:1.1-event -> ../event6 ├── event0 ├── event1 ├── event10 ├── event11 ├── event12 ├── event13 ├── event14 ├── event15 ├── event16 ├── event17 ├── event18 ├── event2 ├── event3 ├── event4 ├── event5 ├── event6 ├── event7 ├── event8 ├── event9 ├── mice └── mouse0 2 directories, 29 files But this command sudo tree /dev/input do not showing any device related to my RFID reader. Hardware: USB RFID reader EM4100 RFID sticker NXP MIFARE Ultralight (Ultralight C) From my understanding, USB should be used as serial library in Python, but the reader act as a HID device. So I tried installing Python library using this command. sudo pip install hid Anyone know how to make the Python script or any guide that might related? I already open this issue on author's GitHub: https://github.com/charlysan/pyrfidhid/issues/8 Thanks. Continue reading...
