Hello, I am Brazilian and I use the CCS compiler and function usb_cdc to communicate by using USB pic.
I am using the PIC18F4550. The problem is: the drivers to install the USB port when I connect the pic is not working. Windows is not using the drivers. The drivers that comes in the folder it does not recognize! I'm using Windows 7 64 Bits. Could you help me? If possible send me the drivers or how I can proceed to solve this problem. Thanks.

Do a search on the forum. The patches needed for the driver on W7, have been posted. Make sure you have _just_ the patched driver in the directory you tell Windows to look into.

Search
"64bit driver"
Select 'find all terms'.
This 'latter', is a vital part of using the CCS search. Otherwise use Google search on the forum (better)....

It should be about the first hit. Thread entitled "USB CDC 32 vs 64 bits".

What is your CCS compiler version ?

Hello, do I have 2 versions: 4105 and 4088.
I do not think that is the problem ...
I do not understand why so much trouble installing this driver, not found anything ....

This will be another win7 issue. Yes it is not just CCS drivers but many others as well. Often it is better to wait several years and let others get the bugs out of a new Windows OS. There is little added value in win7 that makes suffering through the driver issues worth it. I just wiped Win7 and replaced it with winXP now if you have the expensive version of win7 it can run in winXP mode. Win Xp is about to go off maintenance so it is now at its most perfected (bug free) state. In several years when win7 is about to go off maintenance I'll put it back on and install the latest win7 patches.

Understand that windows 7 is very new, but back to the windows xp is a step backwards!
We should encourage and work with 7. is not just back to using XP.

Lucas... Do you have the same problem that I do?
Mine is with Windows 7 64bits.
When the PIC is trying to enumerate it looks that an error happens and the device disconnects and connects again... The VID & PID are zeroed in the device manager.
Did you find a solution for this issue?
On XP 32 bits there are no problems and the PIC is recognized as an serial port.
Can someone help me?
Thanks a lot in advance!

How recent is your compiler?.

The 'inf file' (not really a 'driver', Microsoft supplies the driver, this just tells the computer how to find it), supplied with compilers older than a very few months, does not contain the required OS ID, for the 64bit OS's. The parts that need to be added, _have_ been published here in the past. You need this modified inf file. You also need to ensure, that the inf file your are using, is the _only_ one in the directory your point the Windows installer 'at'. CCS have also done this with the latest inf file, with compiler 4.107, having the inf file in a separate directory, from the one for other OS versions. If it is not in a separate directory, the installer always seems to select the XP install file 'by mistake', and won't allow the device to install.
With the correct inf file, and with it "on it's own" in the directory, it does work (provided of course, that you have a working USB device....).

Hello, I could not solve the problem. I found another solution: Set to use the usb as HID (Human Interface Device). From what I read does not need any driver in the system, because this driver has all systems, it is a driver generico. But I still don't know how to use HID as if by chance anyone knows please help!
It seems that the HID mode is much more versatile and interesting for us!
Thanks
