Discussion - Hardware / Force FT4232H to Full-Speed (12MBit)
« on: February 08, 2021, 11:53:05 AM »
Hello,
I want to force the FT4232 into full-speed mode. But unfortunately I don't know how to do it. I soldered a 1.5k Pullup resistor (3V3) to the D + lead. But this was unsuccessful. I can still measure signals at 480MHz on the data lines. The problem is that my cable is 6m long and therefore 1m too long. Therefore I would like to try it at full speed this should run much more stable than the high speed variant. I can hang the FT4232 on a full-speed hub in the hope that the FT4232H will then run in full-speed mode.
