Hello,
For my custom board i like to remove the software connect/disconnect and only have the 1.5K pull up resistor. must it be pulled up to 3V3 or the 5V from the usb? Kasper2011-05-17 03:37 AM
Hi kasper,
Have a look on Datasheet , Section USB characteristics; D+ Should be pulled to 3V3 volts ( your VDD) . Hope this helps you for your Board design. Cheers, STOne-32.
