Reader USB device

[lizhi0007]

Hi sir,

I have a RFID READer Kit. It has: bInterfaceClass=0x00, bInterfaceSubClass=0x00, bInterfaceProtocol=0x00. In Manage of My Computer, it displays: Microchip Customer Usb Device. I used your example: winusb_cs_181 to try interfacing. Software could receive the kit(insert and remove). But i can't read data from kit. Can you help me to give some ideal for my project? I don't know which reading i have to use (interrupt, Bulk, or click button)? I try to use all of them(reading). But software announce: "Attempted to write or read protected memory. This is often an indication that other memory is corrupt." yellow in "throw".

Please help me.

Thank you.

Include my device driver:

Hi sir,

I don't know which kind of reading method i must to do? Readfile or bulk transfer or interrupt transfer or control transfer,....
Software can detect device to attach or remove.

Thank you for helping.

[Jan Axelson]

Either bDeviceClass or bInterfaceClass should have a value > 0. If it's vendor-defined, it should be FFh.

If you want to use WinUSB to access your own vendor-defined device, you need to create an INF file for it. My application is written for my WinUSB firmware that echoes back received data. To use the application with another device, you will need to edit the application to be compatible with the communication protocols your device's firmware supports.

For more about WinUSB, see:

Hi sir,

I tested my device twice times: by USB View(that i showed to you), and by Visual Basic program. bDeviceClass and bInterfaceClass are zero. I don't know what kind of class. In regedit i saw: class "customUSBdevice". I saw Enum\USB\...

OK, Sir. I used your WINUSB program with {a5dcbf10-6530-11d2-901f-00c04fb951ed}. It just only detect attaching and removing.

For reading(any type)
at "throw" have error : "Attempted write or read protected memory..."
Can you help me what parameter i must change for Bulk transfer with my INF file?

Thanks for helping!!

[Jan Axelson]

Use a buffer large enough to hold the data the device sends. To find out this value, examine the device firmware or whatever other documentation you have for the device.

 According to you, can i change my device driver to WINUSB?  I know WinUsb_Initialize = fail. So, my device isnot WINUSB.
How can i do for changing?

I am stressed with this project....

That is already kit. I cant design firmware again.

[Jan Axelson]

In your first message, you said reads failed. Now you are saying WinusbInitialize fails.

Check Windows device manager to find out if the PC has assigned the winusb driver.

Jan

[lizhi0007]

Hi sir

Thanks a lots.

But i can't find out. It just display "CustomUSBDevice". Reading fails because it isn't WINUSB class, And WinusbIntialize fails.

I will stop, because i can't find reading method.
Thanks.

[Jan Axelson]

In Device Manager, find your device, then click Driver, Driver Details.

Jan

[lizhi0007]

I saw: mchpusb.sys

I use USB VIEW to find out parameter of my device. They are nearly your firmware in C18 HID:
 0x0020
bDeviceClass: 0x00
bDeviceSubClass: 0x00
bDeviceProtocol: 0x00

............

But when i use your software in C#. It can't find out my device.    mchpusb.sys    how do i use it?

Thanks.

[Jan Axelson]

Move or delete the mchpusb INF file.

With the device attached, in Device Manager, right click the device and click Uninstall.

Remove and reattach the device and assign an INF file that assigns WinUSB as the driver.

Jan

[lizhi0007]

It can't. How do you think about difference between firmware(already) and driver (.sys)? I use winusb.sys and MCHPWinUSBDevice.inf instead for  mchpusb.sys and mchpusb.inf, but it can't install.

What is USB interfacing type (?.dll, function?) i must use with mchpusb.sys in C#?

[Jan Axelson]

The setupapi log file might have a clue as to why the driver doesn't install. Search on setupapi log file to find out how.

The Microchip forum is likely the best place for mchpusb questions.
