Cannot Detect device at 0x17

[SifuSteve]

Hi, hoping someone can help here.
I've got a board with several I2C slaves on it.
One has an address with 0x17, and is not recognized via i2c scan or with code.
I'm using a Ft4232H device, and with other code I can recognize this device. (We are moving to a new I2C master access method)

The other odd thing is we've got two devices showing up as R devices, but are not logically on the bus. (0x32 and 0x52)

Here is the i2c scan:

Here is the test code, the mux write is to open all channels to the other I2C devices:

`import sys
import pdb
sys.path.append("C:/Python312/Lib/site-packages/pyftdi")
from pyftdi.ftdi import Ftdi
from pyftdi.i2c import I2cController, I2cIOError

i2c = I2cController()
i2c.configure('ftdi://ftdi:4232:100-121623/1', frequency=100E3)

TI_DCDC = i2c.get_port(0x69)
MUX = i2c.get_port(0x75)
CPLD = i2c.get_port(0x17)
ADC1 = i2c.get_port(0x48)
ADC2 = i2c.get_port(0x49)

MUX.write_to(0x00, b'\xff')
`

Any insight would be greatly appreciated.

Cheers,

Steve
