Dunno if this is of any use to anyone here, but I've managed to convert my Serial cradle for my Compaq iPAQ to USB. I've copied a post to a Brighthand's ( www.brighthand.com ) forum:

Hi all,
I followed the Brighthand's article's instructions on converting the Serial cradle to USB and couldn't get it working at all. Then I found the compaq's detailed specs on their site and after looking at the pin outs of the 12 pin cradle connector and the USB cable, I found that on my cradle, the pin connections were different to what the article on this site said. Working out what pin went where, I found that on the cradle's connector's circuit board, there were the exact connectors for the USB cable - much easier than soldering to the pins on the back of the connector.
Look in this photo:

Now, see the holes in the cirucit board, labelled H1 to H6 - that's where you solder the USB's cables to.
White -> H5
Green -> H6
Red -> H2
Black -> H3
And it worked first time!![](http://forums.murc.ws/ubb/smile.gif)
PS: I bought my iPAQ last week at a Dixon's at lakeside here in the UK.
