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 |
