USB Bootloader CRASH on Vista

[mindthomas]

Hi, i'm new here so i hope you can help me
For two weeks ago i had a great USB Pic18F2550 programmed and worked, both in Bootloader mode (Programming mode),
and it was also running great in Testing mode (I had maked a Visual Basic program, and a PIC Code in Pic Basic, so i could control some LED's)

Then i don't know what i had done, but suddenly when i connect the PIC To USB when the PIC is in Bootload Programming mode, my Windows Vista Home Premium crashed into Blue Screen Of Death, saying that there was a problem with the mchpfsusb.sys driver.
Where in the driver the Error happends is different everytime i try to connect the USB to my computer, but it crashes, and restarts!
The funny thing is that my PIC works in USB Testing mode with my Visual Basic application, but i can't set my PIC into Programming mode without having my computer to crash!!

I hope you can help me, because i have reinstalled my computer last night, because i thought that could fix the problem, but NO.

Best Regards

I know what the problem is!
You have reinstalled the worlds most popular and one of the most expensive, legal, most recognized virus/trojans/malware's ever written and sold commercially for public use. VISTA!

Seriously though... Try connecting your programmer/board to a USB port closest to the motherboard chipset (i.e. in back)... Not the front ports, not a hub, nothing.

And how many other things still work with that particular USB port?

Many things! I am sure that it isn't the USB Port that is the problem, because i can use eg. Mouse, Memorystick, Ext. HDD, IPod and more, on that port!
