I2C issue

Hello,

My flashcatusb classic with last ver 4.40 do not recognize eeprom 24c16, 24c32, 24c64 and 24c128 in i2c mode. Only recognize 24c08.
 
No, the same problem. I selected the correct manufacturer part number. I believe is the vendor, because I tried with the ST vendor 24c32 and 24c08 and recognize them, but with the CSI vendor do not recognize 24c02 and 24c64. Are CSI vendor supported in your eeprom list?
 
The developer has said that all the eeproms should be detectable.
 
That's rare. I tried many times and the same issue. I will try again in other way.
 
Do you perhaps have the datasheets for the Eeproms you are trying to detect ? This way we can forward them on to the developer and he can 100% verify if fcusb is capable of reading / writing to them.
 
Was there any resolution to this CSI issue? I am having the same issue with a CSI 24C03WI . Our old Rev 2.1 board with build 450 software is able to see the device and read/write to it. However with the newer Rev 2.2 boards with build 570 we cannot detect the CSI 24C03WI (On Semiconductor/Catalyst) device. There are I2c EEproms and CSI is being used as a direct drop in for an Amtel part. I can detect and program the Amtel part with both old and new boards. But cannot recognize the CSI parts with the newer board 2.2 and associated driver and software. I have also tried build 528 with the 2.2 board. Same result as build 570. I may have to return the 6 rev 2.2 boards I bought if I can't find a solution to this problem. Why does the older software/HW detect this CSI part and the newer one does not? And what can I do to get it to work with the newer rev HW/software?
