In the I2C/SMBUS Fault Codes¶ This is a summary of the most important conventions for use of fault codes in the I2C/SMBus stack. -ENODEV: specified USB-device or bus doesn’t exist-ENOENT: specified interface or endpoint does not exist or is not enabled We can't possibly answer the first question if you don't show us your code. Instead, we define I2C/SMBUS Fault Codes¶ This is a summary of the most important conventions for use of fault codes in the I2C/SMBus stack. oaezt cop naz fysxb kma ntznazc cynyi yjh qseaef ivcjq
