Question: I want to use CP210x devices with Direct Access Driver (a.k.a: USBXpress Driver) so I download Direct Access Driver from Silicon Labs website, install it, then I change VID/PID of the CP210x devices to 0x10c4/0xEA61. However, I only see one USBXpress device interface for CP2105 or CP2108. Are CP2105/2108 not supported?
Answer: CP2105 and CP2108 device can be used with the USBXpress driver, but these devices must be added by customizing the driver using AN220: USB Driver Customization Software. The AN220SW can be found in this link: https://www.silabs.com/documents/public/example-code/AN220SW.zip
