My Presario 2175 has built in 1.1 usb,  will a 2.0 interface perform at a 2.0 rate?

Do you mean "will a USB2.0 device connect?". Yes at the 1.1 rate, 1.1 speeds are a subset of the 2.0 spec.

Connection isn't the problem. Performance is.  I hope to use the USB pcmcia 2.0 card to achieve 2.0 speeds. the application is bandwith intensive, it is a live sound app.

One review of USB 2.0 cards from 2004 mentions that the speed isn't as good as USB 2.0 on the reviewer's desktop. You'll probably have to do your own test.

I use a 4 port pcmcia usb 2.0 card in my 7 year old usb 1.1 notebook

works well definately faster BUT depending on what you do you may need to utilise the additional external power that a usb 2.0 pc card should come with fortunately mine can take take power from an existing usb 1.1 port apparently come require an AC adapter which isn't useful with a laptop !
