Summary of your problems:
1. Your i430x-chipset based motherboard has most probably a USB 1.x version support. Newer peripherals are at least USB 2.0 spec.
- High speed devices may not work with lower-spec USB interface, whereas low-speed peripherals will work with USB 2.x+ based interface.
2. Unfortunately there may not be a USB-to-Gameport adapter available, but there are Gameport-to-USB adapters available.
- USB-to-Gameport is where you may theoritically use a USB gamepad to connect to a supposed gameport adapter. If this is possible, the adapter will have a base with USB input slot on the adapter, and the wire end will have a 15-pin gameport male connectorto connect to the 15-pin female port commonly seen on the sound cards. I'm not aware if this is available commercially yet.
- Gameport-to-USB adapters are vialable - where you connect the older 15-pin based gameport Joysticks/gamepads to newer systems. The adapter will have a female 15-pin connector on the adpater, and the wire end of it will have the USB connector to connect to a USB port in the newer pc.
Suggested Solution:
1. Use the gamepad with a newer USB 2.0 or higher integrated system.
2. Get a classic Gamport-based controller.

(Keep in mind that there are no dual analog-stick based gamepads which are also gameport varities available as far as I know. So if you're looking for the PS style gamepads, for playing the Tomb Raider using both analog sticks is not possible, yet. Most gameport-based gamepads only have 1 analog stick at most, that I've come across.)
3. Or play the Tomb Raider in a newer system with your new gamepad. Dosbox should be able to play it well in latest systems. I'm not a fan of TR, and so, I'm not sure if fans have created a port executable to help it run natively in Windows.
P.S. Your new gamepad IS a piece of cake when it comes to newer PCs with USB 2.0 and above support. 😁
