Hello,

USB driver requirements are defined in detail in USB spec regarding impedances, voltage levels, rise and fall times, symmetry of differential signals.

LVDS doesn't meet the level requirements, furthermore USB has additional singled ended signaling, that can't be provided by a usual differential driver. For reduced requirements, e. g. short distance interchip USB, you can use two CMOS tristate drivers for USB TX.

Regards,
Frank
