Can a DB9 connector be used as a usb connector

For LS/FS it does not matter, it will work. For HS, it depends on how you wire things up to the connectors. If you plan on also using standard cables, then it may be unstable. If the cable will be actual USB cable just terminated to a different connector, it will likely be fine. And absolutely no for anything USB3. Given that it is a keyboard, it will likely be FS.

USB to 9-Pin Serial Port

That won’t work. USB-to-serial exists because USB devices can be just about anything, and drivers are built into the OS for common devices like serial adapters, floppy drives, etc. Serial-to-USB would require active conversion, with the knowledge of what you are plugging in. You’d need drivers that know how to talk to a floppy drive plugged in that way. More on reddit.com

r/AskElectronics on Reddit: Can a DB9 connector be used as a usb connector

April 21, 2025 -

For a keyboard build iam looking at different connectors I like the look of an db9 connector. Can I use this instead of a usb connector. So the protocol will be usb, cable will also be usb. I'll snip the usb type a of and replace it with a db9 and do this on the keyboard side to. Will this matter For the signal?

Lmao why is everyone hating on this so hard. USB signals get sent over all sorts of non-standard connectors. As someone pointed out many industrial tooling use ruggedised locking connectors on the equipment that terminate with a USB A on the other. OP - yes this can “technically” work if you create a custom connector for your keyboard and recipient device. My only suggestion would be to fill all the unused pins with epoxy so the cable is somewhat keyed to your custom arrangement. Just reduces the chance it gets plugged into the wrong thing one day. But yes, this will work for a flippin keyboard. If it doesn’t - solder on a normal USB A. You had fun trying.
