#TEST SERIAL CONNECTION WINDOWS 7 DRIVERS#
However, In Device Manager the driver is now found under 'Other Devices', although within the properties it says 'The drivers for this device are not installed. If I completely uninstall all drivers and software, then connect the VCDS USB cable to the laptop only, Windows recognizes it and installs a driver, then states 'Setting up a device ROSS-TECH USB' followed by ready to use.
I did notice one thing that was different. I have uninstalled and reinstalled so many times now, but to no avail! My i7 laptop has never had a problem in the past, so assume it is more related to the OS and the VCDS USB drivers. I then tried running the DPInst, but made no difference.
#TEST SERIAL CONNECTION WINDOWS 7 UPDATE#
I have tried selecting Update and pointing to C:\ROSSTECH/ VCDS for driver update, but it says the driver is up to date. If I select properties, it says 'Windows cannot load the device driver for this hardware. In the differential RS-422 and RS-485 communications, you should connect the TXD+ pin to the RXD+ and the TXD- to the RXD. For RS-232 loopback test, you need to connect the transmit (TXD) pin to the receive (RXD) pin. I went into Device Manager and I see Ross-Tech Direct USB interface showing under Universal Serial Bus Controller. This method will let you easily pin down a malfunctioning port and node in a serial device network. USB library version 03.02.07 Interface NOT Found! When I then open the program and select Test, I get the message Ross-Tech USB interface not found. I have installed VCDS 18.9.0, but the USB drivers are not recognized.
Here is a patcher to enable RDP on all versions of Win 7. I do get the light come on when I connect the VCDS HEX CAN cable to the car, so I assume that is ok. Windows 7 Starter, Home Basic and Home Premium can only use Remote Desktop to initiate connection but does not accept connections as this feature is only enabled in the Professional, Ultimate and Enterprise version. Since I have had Windows 10 Enterprise upgrade, I am unable to use it at all.
I have owned my VCDS HEX-USB+CAN for several years now and run it with my previous Windows 7 OS with no issues at all.
