USB Device Unkown with USBUART_1_cdc.inf file
I am working on a project using the USB_UART module, and I am having some difficulties with the device driver.
I have created and used a project for the CY8C58LP module on the CY8CKIT-001 developement kit, and used the USBUART_1_cdc.inf file in it's generated sofware folder. This device driver works, and the PC can connect to the PSoC device just fine.
I've used the same code and USB_UART module for another project (same code, different hardware), this time for the CY8C5666LTI-LP005 chip on a custom PCB. This project compiles and programs to the board just fine. I should note that I am programing this chip with the 5pin Miniprog connected to a custom 5pin cable on a usb micro connector.
Using a separate usb micro cable (which is standard 4 wires) I now try to connect my PC to this device, with the appropriate USBUART_1_cdc.inf file, and I get Device Unknown, even when I try to get the Device manager to specify that custom driver.
Geven that these project are as identical as I can make them, and the USB ports are connected just the same ( D- to P15.7 and D+ to P15.6 for both), and I see appropriate USB signals on my custom pcb, I feel that there might be something wrong with the device driver, given the chip change.
Can anyone recommenced any steps to follow to get this device driver working?
