IMPORTANT: select 'let me pick from a list of device drivers on my computer' IMPORTANT: Select 'Browse my computer for driver software'
go to the device manager and find the unknown device (JM CDC DEMO) and in the driver details, update the drives Under Win7 32bit I pointed to the fsl_ucwxp.inf as delivered in the USB stack, and everything worked fine. I managed to have it compiling and downloading both for my MCF51JM128 and MCF52259 boards, and both on my Win7 32bit and my other Win7 64bit machine a driver installation was showing up under Windows. This might be helpful for everyone having this kind of problems: installing the CDC (aka virtual COM) drivers under Windows 7 and 64bit.įirst: I'm using the USB Stack with PHDC Support from Installed it on my Windows 7 machine (32bit). Is there a way to set up a CDC driver that will appear as a serial port in whatever type of PC (defined above) without the need for special host. I have also searched the FLS forums and tried the trick suggested by BugMan to set the CIC_PROTOCOL_CODE value to AT_250_PROTOCOL as well as trying to associate "usbser.sys" to the "Unknown (USB) Device" in my Windows 7 machine as suggested in the uTasker documentation. I have reviewed the USB.org "Universal Serial Bus Class Definitions for Communications Devices", Revision 1.2 which covers the CDC as well as the USB 2.0 specification and the class definition in virtual_com.c seems to be correct. My understanding is that a device that is set up as with the CDC interface provides this capability - but in the "virtual_com" folder, there is the "inf" folder which contains "fsl_ucwxp.inf" which must be installed on a Windows/XP machine for this to work - when I try it on a Windows 7 PC, I get "Unknown Device" in device manager and Windows 7 will not allow loading "fsl_ucwxp.inf". Windows PCs (various flavours XP, Vista 32 & 64 bit and Windows 7 32 & 64 bit)
The product that this is being designed for will interface to: The goal for this product's USB interface is for the host app to be a single common Java program which runs on the different PCs listed below, opens and tests the different serial interfaces to find the product and start communicating with it.
I am not able to get a connection on a Windows 7 PC. I am running virtual_com successfully on the M52223EVB and I am communicating with a Windows/XP PC using Tera Term. I am using the "virtual_com" example app that comes with MQX 3.6.
I want to use the MQX USB driver configured as a CDC device.
