USB DRIVER PROBLEM
PostPosted: Fri Nov 10, 2006 6:23 am     Reply with quote
Hi,

I configured a PIC18F4550 with Microchip bootloader. My problem is that does not recognize the USB driver.

When I reset my PIC, windows detect a new "unknow" device ant it appear as "? USB device". Then when I select "Update driver" and select the USB driver, it tell me: "The specified location does no contain information aout your hardware"

I tried with windows 2000 and XP with similar results.
I revised the correct pinout and VBUS level is 3,3 V.

Can anybody help me?

Thank you
