AS3992 UHF reader to connect to USB
Why not make or buy the reference board?

I try to write GUI to interface with this board by using C sharp. Could you give me some advice? I connect USB to Reader Board and try to send and receive data from Tag (SL900A)
I built a GUI to interface with UHF RFID reader AS3992. Although the firmware detect devices but I cannot send data to this reader to get value back. Anyone help me?
what is the error message shown when you insert the usb cable?
I send you my problem. Although I can detect the device but I cannot sent data.
If you want I can give you all of my working.
Dear Sir, I have checked on Proteus and it worked with virtual USB. This is my result.
after connecting , did your device is shown in system HW list of the OS?
first make sure that the device is in the list.
then debug the cause one by one.
Dear Sir.
Because my programe just recognize only one USB device based on PID and VID. So I think that is not a problem. I cannot look into RFID reader so I cannot debug Sir. Could you give me any advice?
I have the firmware of AS3992 and the User Interface from manufacture. I am newbie in RFID area so Sir help me.
Now the warning disapper but I still cannot send data to RFID reader (C8051F430).
after making sure that the device is shown in , 'the windows -device manager list',
assuming that your device is programmed with hid hex file,
the application can start reading the Report in and write the report out structure.
if everything is OK , then check your application flow for your requirement.
But I don't know the reason why my programming does not work although I tested on Proteus. The difference in here is two kind of microcontroller C8051 and PIC18F4550. I used HIDUSBNetClass, VC2012.
I recognise that C8051F340 does not compatible with HID USB. I search that USBXpress is developed by Silab can be apply to this. But at that time I have a problem with installation this software.
