Title: USB Interface device not recognized
Post by: GarberFC on January 09, 2009, 08:03:44 AM
Hello All,

I just reinstalled XP. I'm all caught up with all the MS updates.

When I plug in the interface (USB) XP tells me it doesn't recognize the device. Is there a special driver I need to install?

All help is appreciated,

Frank  >!

Unplug the USB Cable from the CM15A to the Computer.    DO NOT OPEN AHP YET.  Shut the PC down.   How, plug the USB cable back into the PC and restart the PC.  When Windows has loaded, go into the Control Panel and go to the System Icon, then when the System Properties window opens , click on Hardware, when that opens, click on Device Manager, then drill down to  Universal Serial Bus controllers. Expand it.  At the bottom of the list it should show "X10 USB Active Home (ACPI-compliant). That's the CM15A.

If it does not show up, you either have a bad USB port or a bad CM15A.

And if that don't work,

This is weird but it works.

Unplug the usb cable from the cm15.
Unplug it from the wall
Remove a couple of it's batteries.
Sit there looking at it thinking "Stupid bitman, this won't work"...
Put the batteries back in
plug it into the wall
plug the usb cable back in

Watch as XP now detects a cm15a (acpi compliant) device.  ::)


I saw this procedure posted elsewhere by I believe the great and helpful Puck.
Darned if it didn't work!

What you did was hard reset the CM15A.
It uses a microcontroller IC to do all the work. Including the USB Interface. If it gets lost. It is possible the USB Port is not responding correctly.

I have seen a post here where an Electronic Engineer add some decoupling capacitors to the Logic Chips to make it much better. You rarely see any digital designs where decoupling caps are not in the design.

Thanks Dan!

It all started working again on the first try. I owe you...  ;)
