fooling usb advanced

is there any way to fool a usb host that it's still attached to a usb hub given that Vbus+Gnd are attached, and milisecond disconnects on D+,D-? How about a pull-up on D+ on the host side

There is a pull down on the host side.
It must be a voltage difference between the D+ and D- for the host to recognize the device.
You can try to pull up the 1.5k to 3.3V.
But the host will stop the enumeration after 3 attempts or 5 seconds
