TECHTOO 4 Port Professional FTDI CHIP USB to Serial RS232 DB9 Adapter Converter Serial Cable 9-Pin Male to Male with Thumbscrews Review: Excellent Product for Remote Serial Port Access of Network Devices - I needed to have remote access to few network devices for remote staging and configuration and plugged into a compact PC running a remote access software on it, I now have access to 4 of routers and switches that I needed to configure. I am sure if you have more than 4 devices to handle, multiple of this product can be plugged into USB ports and it then replaces a terminal server. I really like this and will probably order another one. Review: Windows 10 No Installation Required - Tech Support not rated as it was not needed. Arrived on time and was an easy plug and play install

Great adapter
Excellent USB to 4 serial pory adapter. Drivers work great and support permanent COM assignment. So no matter which USB port you use, the COM number will always be the same. Only issue I had was that the numeric labels did not match the COM port numbers assigned by Windows 10.

Great tool
Very stable, was able to console into a switch, firewall and two controllers at the same time, very useful!

Here's detailed (Linux) driver/device info
When buying "generic" computer hardware like this I often wish someone would post some technical details so that I can make a better guess regarding whether or not it's going to work for me. I bought one of these for use on a RPi-based test fixture, and so far I have not run into problems. I did not need the driver disc at all -- just worked out of the box on Debian Linux (wheezy & stretch). `lsusb` outputs the following: Bus 003 Device 012: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 003 Device 011: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 003 Device 010: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 003 Device 009: ID 0403:6001 Future Technology Devices International, Ltd FT232 USB-Serial (UART) IC Bus 003 Device 008: ID 1a40:0101 Terminus Technology Inc.
