Select Install this driver software anyway. A Windows Security Dialog Box will now appear.Click on Next to continue and again click on the Next button.Then click on the Have Disk option and locate the Android CDC Driver on your PC.Now, click on Show All Devices and click on the Next button.Now, click on Action Menu from the top bar and select Add Legacy Hardware.It will give you the search result and just click on it. Next, open the Device Manager on your computer by pressing the dedicated Win button and type the device manager in the search bar.First, download and extract the CDC Driver on your Windows PC or Laptop normally.Not to mention that USB was being touted as the solution for embedded developers to the dropping of serial ports by manufacturers, now its just started being taken up and it suddenly becomes useless again with an upgrade to 7 without extra hardware or expensive licensed third party drivers? There are third party virtual serial drivers available (generic drivers that are compatible with any CDC implementation) but the licenses run at about 3000euro from some companies. I have been using XP Mode so far and it connects OK but its a little difficult to develop the application to drive the device via the virtual serial port and then have the device connect to, what might as well be, a completely different computer. Serial.SvcDesc = "USB Serial emulation driver" HKR,EnumPropPages32,"MsPorts.dll,SerialPortPropPageProvider"ĪddService = usbser, 0x00000002, Service_Inst This is the original INF that worked with XP does anyone know how to do the same in 7?: Windows 2000 and XP setup File for AT32UC3 demoĬlassGuid= I have a hard time believing that MS just removed all this functionality from the USB stack/drivers in 7 so there must be a way to set this up just as it was done in XP but I don't know enough about the INF files to see why mine no longer works. Now Ive upgraded to Windows 7 and the INF no longer works, when I try and 'add legacy hardware' I just receive a message that a suitable driver could not be found. This device implements the CDC services that are required to make a simple serial connection and under XP the driver was simply an INF which instructed the OS to create a virtual serial port using the standard USB drivers.
Hi, I have a USB CDC (communications device class) device (Atmel microcontroller) that I want to communicate with via USB.
