1. No software known upgrades USB 1 to 2 or 3.
2. http://www.docs.sony.com/release/specs/PCGFX310_mksp.pdf notes it has a PC-Card slot. Here's an example USB 2.0 PC-Card.
There are others like that so shop around.
My Sony Vaio laptop, model PCG-FX310, W-XP, has USB Ver 1.1.
I need to upgrade to Ver 2.0.
Is this a hardware difference that can be modified?
Or is it a software (controller or driver) issue that can be upgraded?
Or, worst case, is it something that can not be changed?
I appreciate any help available.
