I am a bit confused about USB Softconnect.
Is the circuitry to turn off the USB+ against 3.3 V resistor mandatory ? Id like to simply tie a fixed resistor instead. Is that possible? Are there any disadvantages to expect?
What impedance is correct, I found values between 800 and 1500 Ohm, so is 1200 the best choice?
many thanx in advance (Tsuneo ? ;), as usual Uli
Ah, power-up delay is applied just for bus-powered device - supplied power from USB VBUS. Self-powered device doesn't care of this delay.

Thanks Tsuneo, you've been such a help, as usual ;)
So I will fix the 1k5.
be well Uli
