18f4550 usb weird problem |

hello all
I am trying to implement ex_usb_serial.c in ccs examples with 18f4550. The code compiles and works very fine till enumeration, then n there stops
The driver supplied doesn't get installed. After a deep search i found the device parameters supplied and detected varies which aries the driver incompatibility.
the detected device class GUID(from devicemanager)
{36fc9e60-c465-11cf-8056-444553540000}
supplied(in driver)
{4D36E978-E325-11CE-BFC1-08002BE10318}
class detected(from device manager)
USB
supplied(in driver)3
ports
compiler 4.09
How am i supposed to correct these errors and make my driver install?
also
When i replace the class guid in the driver with that of device manager the driver detects the the device shows "USB TO UART" but doesn't start, puts up some error code. |
