Hi,
I'm pretty sure it's a high speed port. Device manager reports it as
an EHCI, and with my pocket drive (USB2->SATA) I get 15M bytes/second
transfer rates.
What would I look for in the descriptors? And yes, that was a typo.
Oops.

Are you sure that its a high speed port and that your descriptors are
correct? (Apologies for any egg sucking)

Surely not quite /that/ fast :-)

The answer didn't leap out at me from the data sheet, so...
I'm working on a Cypress-FX2 based board, and the driver has decided
to bring the link up in full-speed mode rather than high-speed mode.
Can anyone offer some pointers on how to force it to high-speed? The
port does work at 4800Mbps, But I've never seen it do that with this
FX2.
TIA,
G.
