For PCB design recommendations, when talking about USB 2.0 High-Speed devices, I suggest you to download the following:

1) http://www.usb.org/developer...g_r1_0.pdf
2) http://www.cypress.com/cfuploads...usbpcb.pdf
3) http://www.cypress.com/cfuploads...X2_PCB.pdf

The last one is concentrated more on Cypress EZ-USB FX2 uC, but it has some useful information for PCB design that I think can be applied to other USB 2.0 High-Speed devices. But, as Andy said, you should always start from the horse's mouth: The manufacturer's website!



What exactly do you mean by that? As far as I remember, TUSB3210 is USB 2.0 compatible, but it supports only Full-Speed (12Mbps). TUSB6250 is the one from Texas Instruments that supports the High-Speed (480Mbps).

I think that Full-Speed USB devices work pretty well with plain double-sided PCBs, but again check the manufacturer's website for more information...!
