I am not buying it; but it's their product, I guess they should know. However, since you don't have any spare slot for a usb2 card, it's moot point anyway.
I have a Dell Dimension 4300S which is about 1 1/2 years old. I want to change my old USB 1.1 to USB 2.0 There are no spare PCI slots. Dell tells me that the 4300S does not support USB 2.0 PERIOD. There was nothing I could do to change the USB. I find this hard to beleive. I'd really appreciate any comments. Thanks
