[usb] question about usb hub remote wakeup resume signaling

["M Dennis" <mdennis97@hotmail.com>]

hi, all

I am confused by Figure 11-10 of usb 1.1 spec. on page 254. Any answer will 
be appriciated sincerely.
My question is about the reflection of Hub B:
the device drived the resume at t0. According to the spec.,after100us,Hub B 
will drive resume on all of its enabled upstream and downstrem ports 
including the port that initiated the resume signaling.That is,the usb D+ 
and D- will be drived by Hub B and the device simultaneously between t1 and 
t3.This will be a severe conflict on this shared bus!?
I cannot understand this by myself.Please Help!

Regards

M.Dennis
