Why does usb port supports only 127 devices?
It is an addressing limitation of the protocol. Theoretically it could handle 127 devices (The initial port/controller/hub is considered 1, otherwise it would be 128) but in reality you would run out of bandwidth long before you got to that point. Any usefulness of a chain of that size would be suspect at best.

In many ways, computer hardware and operating systems grow together - changes in hardware have to be accomodated by changes in the operating system to support them, conversely the way the operating system uses the hardware may well influence hardware designers to improve aspects of their work.
Example
When Windows XP was released, DVD writers were fairly rare and expensive devices and XP did not directly support them; third party writing software had to be used. When Vista was released, the operating system accomodated the new hardware.
Conversely, Windows computers rely heavily on DirectX technology for graphics. Video adaptor designers specifically try to make their devices so they run DirectX well.
Computer companies such as IBM and Apple produce both the computer and the operating systems, so they can more tightly couple the two together for simpler operation.
