SOURCE: Detect camera in Hp Ipaq hw6515 PPC

I have been working on Camera cell phones and see these kinds of issues. I am afraid that your camera interface was bad and the phone main board is not recognize the connected camera. I don;t think this is a software isue when it error message said connect the camera or reset pc.. If you are not think my suggestion is correct, you may try the other way by flashing the ROM as updating the new ROM version, it may also hlep to solve this issue and if it is still not, then I am sure th efaulty is from your camera. This is an comment issue in most camera phones I have been fixed before. I hope it help.

I had same problem.
Culprint was in the back cover.

Above SIM holder is a hidden switch what will connect the backup battery when the main battery is removed.
Small hook (high up) in the cover will trigger the switch. When cover get loose the switch will change it's position.

I put small piece of shrinking tube in it what will extend it 0.5 mm. That did the trick. No more unscheduled reboots.

Get the correct settings from your service provider, though most have an automatic service for this. Go start - settings - phone - network tab. and enter the settings

The HP IPAQ 6515 will support WLAN access via a SDIO WIFI card (which looks like a 'long' standard SD card): it is just a bit tricky to get this add-onl SDIO WIFI card to work properly!
