Hello.

we need PCI so Au15xx is our only choice. Internal USB 1.1 is working well,
but what about adding a PCI to USB controller? Has anyone tried this?

Our Au1500 board works fine with Ricoh CardBus Bridge and NEC USB controller.
However, the board does not work stably with TI PCI1520 controller.

~# lspci 00:0a.0 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev 82)
00:0a.1 CardBus bridge: Ricoh Co Ltd RL5c476 II (rev 82)
00:0b.0 RAID bus controller: Triones Technologies, Inc. HPT371/371N (rev 02)
05:00.0 USB Controller: NEC Corporation USB (rev 43)
05:00.1 USB Controller: NEC Corporation USB (rev 43)
05:00.2 USB Controller: NEC Corporation USB 2.0 (rev 04)

What I don't understand is why use USB card on CardBus, if the Au1500 datasheet clearly tells us (well, at least me :-) that this is *not* going to work?

WBR, Sergei
