USB Device Not Enumerated

[Imad84]

Hello,

I am using the PIDEM FS USB demonstration board from microchip with the PIC18F4550

My code has no errors but it stops on the usb_wait_for_enumeration()
function and the system (windows XP) gives the following message:

USB device not recognized.

Any Help

Thanx

Which demo?.
For the basic 'HID' device, the driver should already be present in XP. However for the bulk device, the XP driver has to be installed.
Look at the appendices in the manual for how to install the devices.

Hello,

I am trying now to compile ex_usb_scop.c

no errors but the system try to install the USB Bulk demo driver but doesn t find it.

in the top of this example it s noted that this example will run on CCS's USB prototype board

is this because i am using another development board?

Any Help or suggestions?

Thanx

You need to install the bulk usb driver. The install, won't automatically 'find' it, you need to point the OS at the directory containing it. Look for the file 'BulkUSBDemo.inf', in the installed software. Point the OS at this, when it asks for the driver, and then when it asks for 'USBDemo.sys', point it at this (it is in the same directory).
No, it is not because of the different hardware, it is because you don't have the XP driver installed.

Did it work when you bought it and plugged it in the first time? The reason I ask this is that the PICDEM FS is configured for high speed operation off the shelf. It won't work on a USB 1.1 port straight away.
