Currently, I am using PIC 18LF4550(http://www.kynix.com/Detail/629145/PIC18LF4550-I%2FPT.html) that communicates with notebook PC which is running XP. I'm in process to upgrade to Windows 10 OS from Windows XP and now my USB device that runs the PIC 8LF4550 is no longer communicating with Windows 10 OS. I tried to look for the driver on MicroChip's website but I am not finding any luck. Any idea where I can get the PIC 8LF4550 driver that supports Windows 10 OS?
the PIC 18LF4550 is the device that runs the embedded CSCI
- HMI CSC is SW that communicates with embedded CSCI using USB.
- HMI CSC is running on Windows XP everything is operating normally.
- when reinstalling the HMI CSC on Windows 10 laptop the USB communication b/w HMI CSC and embedded CSCI drops
- Transferred all the drivers from Windows XP to Windows 10 laptop without any success
- thus leading to PIC 18LF4550 driver that can operate with Windows 10
I am using a host application (Developed with C# in Visual Studio) running on a 32-bit Windows XP Service Pack 2 to connect to the PIC device.
When the host application is moved to 64-bit Windows 10, the host application will not connect to the same PIC device, even when the application is launched with Windows XP compatibility settings.
On both machines, the PIC device is recognized as a Human Interface Device in the Device Manager.
On the XP as: "HID-Compliant Device" and "USB Human Interface Device"
And on the WIN10 Machine as: "HID-compliant vendor-defined device" and "USB Input Device"
Under driver details:
For the XP-machine, under driver details of the "USB Human Interface Device" I have: hidclass.sys, hidparse.sys, hidusb.sys, and hid.dll.
On the WIN10 Machine, under driver details of the "USB Input Device" I have: hidclass.sys, hidparse.sys, and hidusb.sys.
The WIN10 Machine does not list hid.dll. Could that potentially be the issue? Or any other ideas?
I appreciate any other guidance you can provide. Thanks in advance.
