So you are looking for a good low-cost USB Serial adapter (RS232) and you are asking yourself "Will a $10 USB Serial adapter cable work with my device? and will it work with Windows 10 and 11?!" Well read on and find out why you have to be careful about which adapter you choose.

Why many low-cost USB Serial adapter cables does not work with Windows 10 and 11.
The reason why many USB Serial adapters does not work with Windows 10 and 11 is because these adapters are made with a low-cost processor chip which complies only with the minimum requirements or less. The physical quality of the processor chip is usually of average quality however the drivers for the chipset are often poorly written programs which makes the USB serial adapter unstable and unreliable and not fully compatible with Windows 8 and other current operating systems. Because of this you will in many cases be unable to make a low-cost USB serial adapter work with Windows 10 and 11 or even earlier versions of Windows and you can expect some of the following typical errors:

  • Computer freeze
  • Invalid debug DLL
  • Computer crashing
  • Driver problems
  • Unable to communicate
  • Unable to establish a COM port
