VIA USB Controller - (Wrong ID) ??

VIA USB Controller - (Wrong ID) ??

[Jesper Juhl]

I've just noticed that my USB controller(s) show up as having "Wrong
ID" and now I'm wondering what exactely that means and what I can do
about it  (kernel 2.6.13-rc6-mm1 in case it matters).

Is it a wrong PCI ID? If so, how's the controller recognized at all?

I stopped by http://pci-ids.ucw.cz/iii// which had an entry saying :

0925	VIA Technologies, Inc. (Wrong ID)
    	Wrong ID used in subsystem ID of VIA USB controllers.

but that doesn't whed much light for me.


Here's a snippet from lspci : 

00:04.2 USB Controller: VIA Technologies, Inc. VT6202 [USB 2.0
controller] (rev 16) (prog-if 00 [UHCI])
        Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop-
ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium
>TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32, cache line size 08
        Interrupt: pin D routed to IRQ 3
        Region 4: I/O ports at d400 [size=32]
        Capabilities: <available only to root>

00:04.3 USB Controller: VIA Technologies, Inc. VT6202 [USB 2.0
controller] (rev 16) (prog-if 00 [UHCI])
        Subsystem: VIA Technologies, Inc. (Wrong ID) USB Controller
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV+ VGASnoop-
ParErr- Stepping- SERR- FastB2B-
        Status: Cap+ 66Mhz- UDF- FastB2B- ParErr- DEVSEL=medium
>TAbort- <TAbort- <MAbort- >SERR- <PERR-
        Latency: 32, cache line size 08
        Interrupt: pin D routed to IRQ 3
        Region 4: I/O ports at d000 [size=32]
        Capabilities: <available only to root>


Can anyone explain this to me?     The controllers are working just
fine, so it's not too important, I'm just a currious nature :)

I've never heard of this before. However, cheking the list shows that 
every vendor which has a "Wrong ID" entry also a normal one. So my guess 
is that "wrong ID" means that somewhere in the process of putting the 
PCI ID (during the design of the device) someone mistook which ID to 
put. So this would mean that your device doesn't have the official ID of 
VIA, but it uses an unofficial one (famous enough to be listed though). 
Nothing to worry about.

Well, as I said before, it's just pure guess, but it's cool to invent 
stories ;-)

It's a correct guess, though. They mixed up the vendor and device IDs in
the subsystem ID of their USB controllers.
