| CDC Bootloader problem |
 Posted: Thu Dec 29, 2016 4:21 am |

Hi,
I'm using CCS compiler v5.015 and I'm using Window 7 64bit.
I've tried to install the driver when it prompt "CDC Bootloader" at my device manager. I've pointed it to the "Driver" folder in my PICC and try to install it. The problem is, it will indicate "Windows was unable to install your CDC Bootloader".
Please help me how to solve this problem.
This is the cdc_NTXPVista78.INF file:

It sounds as if you are not pointing at the correct driver, or your 'build' used the usb_desc_cdc.h file from an earlier version.
In CCS V5.013, the VID was changed from 0x461 to 0x2405. This later VID, CCS bought, and Microsoft then allowed them to include a .cat file with the driver, so it is seen as a 'signed' driver.
Now the inf file you post is the correct one for a post 5.013 build. However if your compile used the descriptor file from before this, it won't be recognised. Is the .cat file present in the directory with the inf file. It is needed.
In device manager, look at the device (will be marked with an exclamation mark, since there is no driver). What VID does it show?. it should be 2405. If it isn't, then your build used the old descriptor file.
Look at this thread:
<http://www.ccsinfo.com/forum/viewtopic.php?t=55524&highlight=usb+bootloader>
You will see that when he rebuilt making sure he was using all the newer files, it then worked. |

Hi Ttelmah,
Yes, there is a cdc_ntxpvista78.cat file in the folder.
I've look in the device manager and it shows the CDC Bootloader with exclamation mark but there is no VID decription.
I've checked the usb_desc_cdc.h, and it show 0x0461.
Do I need to change it to 0x2405 to make it work?

Why don't you try it ? These are the values used in the current version
of the compiler, vs. 5.066. Try it and tell us what happens.
| Code: | #define USB_CONFIG_PID 0x000B

Whoa a second.
The descriptor file you are posting is _not_ the one used by the bootloader. The bootloader uses use_desc_cdcboot.h
If you are using the standard serial descriptor, then 'no wonder' it won't work.
The descriptor for the bootloader (from your compiler version), is:

You will see that the device ID is different from the standard serial device (which is the numbers PCM_Programmer posted).
Understand that with 'signed drivers', everything must match, or Windows will not accept them. |

Hai Ttelmah and PCM,
Thank you very much both of you, I rewrite again the program and point to the correct usb_desc_cdc.h and it works. Right now I'm testing using windows 7 32 bit.... maybe tomorrow I will test it on 64 bit.
Thanks again |
