An update: No matter what register I am trying to read in the BMP280, it returns the correct value on the logic analyser, but the DeviceRead vi always reads 0xFF

Hi I am using the MPSSE I2C drivers over a USB FT232H device, communicating with BMP280. When I read the BMP280 device ID, it is supposed to return 0x58 but the DeviceRead vi returns 0xFF. I have used a logic analyser and can confirm that the device is actually sending 0x58, but the output from the read vi is 0xFF. Has anyone had this same problem, or can anyone suggest what might be the issue? Thanks Arj
