Greetings

I have an HP Envy with Windows 7 professional.  Device manager does not show the usual com and Lpt port icon.   I need to access a device through a serial connection.  I have the USB to serial converter, but I need to enable the serial port in devices.  

Thanks

It has been a while since I have done this, but the USB converter came with software to install that facilitated the connection.

I routinely use a USB to Parallel cable and the printer shows up on a USB port in Windows 7, not a printer (LPT) port.

No, I am afraid the converter did not come with any software.

The USB converter cables. I would try two things:

1. See if the connected application can adapt to the USB device driver.
2. See if you can get different cable that comes with software to help make the connection.

I should also note (from personal experience) that those USB <--> Serial cables are not all created equal. In my experience (RF radio applications), some cables work and some don't.  ... Thinkpads_User

Most are developed for the OEM market by Future Technology Devices International Limited.
