Where can I find a driver for HP jornada 520 to Windows 7

I agree a clean install is always the better, fresh start J
OK it sounds like missing drivers, what you have to do is create a new installation CD that will load the drivers for your laptop as it boots. I haven’t try this method with windows 7, but I know it works well with Windows XP. Try and create a new Windows XP CD with the drivers see: http://unattended.msfn.org/unattended.xp/view/web/35/
The start a new installation with this Windows XP CD and reformat you computer, after that you can do a new upgrade to windows 7

The HP Jornada 520 Series Pocket PC has been discontinued, and some of the accessories may be difficult to locate. They may be available in one of the following ways:

• Contact an authorized HP reseller and give them the part number.
• Order the parts from HP PartSurfer .

The Part No. for your Serial Cable = F1819A
Hp Internal Crew No. for your Cable = F1798-80014

It's built into the system...

Try this link that describes the error you are seeing... http://support.microsoft.com/default.aspx?scid=kb;EN-US;q271300&GSSNB=1

All you have to do: Select Device Manager, select "Universal Serial Bus controlled". Re-install the USB driver from Active-Sync CD. That's it.

This may be a simple case of removing all the entire active sync directory. If you used to connect via serial+com it wont be detected on usb. Remove active sync from your pc via the add remove program feture, then reboot and re install. Then run the make a connection again from active sync. Hope this helps
