usbhost.exe erroor opening device

I am using Windows 10, I have the drivers installed and I see the device in my device manager. I have also gotten to the point of trying to talk to the usb through usbhost.exe however, when I run the program it gives me an output of:

USB Bus: bus-0
USB Device: 0x10c4:0x0001
Error opening device: No error

 

Is it a driver error, or is it a connection error?

Could I know which part you are using?

Is this is a USB bridge part like CP210x? is the board you are testing a evaluation board from Silabs or made my yourself?

 

If this is a MCU part with USB function from Silabs, what software you have programmed into it?

 

I am not familiar with usbhost.exe tool, is it a free test tool, where you get it?

Re: usbhost.exe erroor opening device

I am using EFM32GG3301024. The board is not an evaluation board. I have programmed the device with the usbconfig.h, my program, the descriptors. I also have programmed my device with a USB bootloader. I know the boot loader and my program are running together. I got usbhost.exe from AN0065.
