Look into the properties of that unknown device. What are its hardware IDs? For the MSP430 BSL, they must be 2047:0200.

There must be HF XT2 present on board, with value supported by BSL. Typical values for default TI HID BSL are 4/8/12/24 MHz.

You can also test USB part of your device with some of HID / CDC examples from TI USB stack, flashed by FET using SBW / JTAG.

4.092 MHz XT2 with 1688 ppm error should work with USB, but just to be sure try device with replaced XT2 with 4 / 8 / 12 / 24 MHz.

Does your own USB firmware work when you do not press the BSL button?
