Im using Window ME with Pentium III which comes with usb 1.1 and wanted to upgraded it with a PCI card to full speed usb 2.0.
Is it possible for this kind of upgrade and does the usb 2.0 port works well in Window ME and will be runs at full speed usb 2.0.[/quote]Installing a PCI USB2.0 card is no problem.
Make sure, it has a NEC chipset since these are those with least compatibility problems. This is important since there are sometimes issues with older mainboard chipsets and some USB cards.
Also make sure, the card comes with drivers (or at least they should be available on the manufacturer’s support website). This is important, since some manufacturers stopped supporting Win98/ME and don’t add a driver disc to their cards. With some Goooogling, you might find drivers, but haveing them at hand immediately after installing the hardware is much more convenient.
About speed: Don’t expect more than 15 or 16 MBytes/sec (with NEC based card, Ali and possibly Via may be even slower).
