Subject: [9fans] VT6306 chip is for OHCI or UHCI?
Topicbox-Message-UUID: d82a1dbe-eacd-11e9-9e20-41e7f4b1d025

I got today a USB2.0/IEE1394 interface card probably Japanese local
card, named IFC-PCI7IU2, which is claimed by the user interface to be
VIA OHCI Compliant.   The card uses VT6306 and VT6212 chip.

I tested this card on my desktop machine, and Plan 9 recognized the
USB interface normally.   I'm now confused much.   The Plan 9's USB
driver is for UHCI programming interface.   Then, why this VT6306
card can be recognized by that Plan 9 driver?   Someone more familiar
with USB, please let me know what is going here...
