USB hub only 1.1 compatible? Answered

Hi, After looking at this USB hub microcontroller page I saw a part where it said this "The TUSB2077A hub is a 3.3-V CMOS device that provides up to seven downstream ports in compliance with the USB version 1.1 specification"

Does that mean it's only USB 1.1 compatible?

that would be my guess, i dont see it anywhere saying 2.0 or 3.0 and 1.1 and whilst 2.0 is compatible (i think, but don't quote me on that) with 1.1, its going to be a tad slower

Oh, Okay, thanks, I will see what everyone else thinks although it does seem to only be 1.1 compatible...

I'm guessing it's only 1.1 compatible, yeah. People are going to be pretty mad at us if we only use USB 1.1. I'll help look for another one. There's got to be one somewhere. But didn't we find out that we won't need a seven-port one? Aren't we just going to use the northbridge ports?

Yeah, We were going to use the southbridge (yes it's the southbridge not the northbridge :-P) ports, but the 7 port was going to be one for the expansion...

Although the southbridge needs to be matched with the northbridge and the CPU and that southbridge with 8 USB ports was for one of the processors that we haven't decided to use yet, so the other southbridge will probably be different...
