Ray, this is exactly why I want to open up the EPR and see what is inside for the USB port. I also want to see what signal is sent on pin 68 of the docking connector (DOCDET). I think this is the Dock Detect command to tell the Libretto to turn on the USB chips on the motherboard, as well as other circuits associated with the docking station. If the drivers are in the EPR, I will also see them.

However, the Libretto doesn't turn the USB controller on unless it detects that the EPR is connected and has external power, probably because the USB line driver requires a fair amount of power to run (because the USB standard requires that the port be able to supply 500mA of current). If someone can both: A: Connect a line driver to the USB lines on the Libretto B: Trick the Libretto into either thinking a powered EPR was connected or force the USB controller to turn on Then it will be possible to use the Libretto's onboard USB without the EPR .... but given the availability and cheapness of Cardbus USB cards I'm not sure it's really worth the bother ... - Raymond At 09:56 AM 16/03/2005 -0800, you wrote: >Date: Wed, 16 Mar 2005 19:55:40 +0200 >From: John Niemi <[EMAIL PROTECTED]> >Subject: About Libretto and USB > >Silly question maybe but I'd like to know; I heard that one of the port >replicators for Libretto has a USB port, is that true? > >And if it is, wouldn't it be possible to make a home-made port >replicator with just USB connection that would be smaller than the full >Toshiba port replicator? > >I just want a USB connection on my Libretto AND keep things still >small, the easiest way would be to buy a PCMCIA card but I want to know >all the alternatives before I do that.
