| problems USB CDC WINDOWS 7 64 bits |

hi everybody
Currently I have problems with recognizing the PIC18f4550 with the Device Manager on my computer windows 7 - 64bit
Explain the problematic:
I started the project two years ago with XP and both "bootloader_usb" as the main "USB-CDC" program worked correctly (COM7 "bootloader_usb" and COM8 "USB-CDC").
Now with windows 7-64bit, the device manager only identifies the usb_bootloader as COM7, but when the PIC works with the main progam (USB-CDC) shows "unknown device".
It's rare but if I load it from XP and I check the device manager in W7-64bit if it works.
Perform a FILE COMPARE with the same compiled program HEX (hex-XP / hex-W7-64bits), that if they are different in a few lines ..... ppppffff
CCS version 4.125
Anyone can guide me
THKS  |

Your compiler is late enough, that it should include the 64bit driver. You _manually_ have to point the device at the file though.
It sits in the CCS director/driver/NT,2000,XP,VISTA,7
and is called cdc_NTXPVista.inf
Go to the unknown device, select 'update driver', and then browse to this file and select it. Hopefully the device will then be recognised. |
