Fixing Windows Mobile GPS Intermediate driver

A week ago I noticed that some applications on my Windows Mobile 6.5 device stopped acquiring a GPS position where other applications did not have any problem at all. A quick test learned me that my WM managed GPS COM-port stopped sending data even tough everything was setup correctly.

After looking around a little bit on the internet I found this interesting registry key and a list of default values too:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers

Using TotalCommander I started checking the values and noticed that both InputBufferSize and OutputBufferSize where set to 0. After changing these values, and those residing in the QUALGPSHarware key*, to 4096 and after rebooting my device, the GPS Intermediate Driver started working again.

*chances are that you have a different GPS(driver)
