How to detect specific chipset in USB driver?

NTDEV
1

I’d need to detect if my USB driver is running on a computer with VIA chipset. It is nothing I’d like to do but there is a problem with remote wakeup which occurs only on these machines when running Vista and I need to solve it some way ASAP. I can use a workaround for this purpose but we can’t afford to enable it globally (and reduce battery life at notebooks by 10%). The workaround is to disable selective suspend so remote wakeup won’t be needed. I don’t see a way how to detect remote wakeup isn’t working so I ponder to make decision based on chipset. Unfortunately, the decision has to be made by the driver not by user mode software where it’d be rather easy.

Ideas welcome.

Can your installer figure this out at install time and then put a reg
value down for your driver?

What should I look for? Scan PCI from BusNumber 0 and SlotNumber 0 and check for VIA VID? Or something more clever?

BTW, it’d be probably sufficient if I’m able to find to which USB HC is my device attached and if it is VIA, enable workaround.

We don’t have one installer; we have many and our customers write their own. That’s the reason why it should be handled in the driver itself. Maybe I could write a coinstaller which’d be called when driver is installed but it looks like real PITA and I don’t have time for it now.

Also, somebody at MS put the driver to Windows Update (although we forbid it) and XP signed version is automatically installed at Vista (:-O) when the device is plugged in…

You would need a blind scan since the driver wouldn’t have knowledge of
the connection topology.

BTW, it’d be probably sufficient if I’m able to find to which USB HC
is my
device attached and if it is VIA, enable workaround.

I’m not sure if there is private channel for USB driver to ping their
HC.

Well, USB_BUS_INTERFACE_USBDI_V3 in the WDK there is a function pointer
which can give you the PCI info for the HC.

PUSB_BUSIFFN_QUERY_CONTROLLER_TYPE QueryControllerType;

NTSTATUS
(*PUSB_BUSIFFN_QUERY_CONTROLLER_TYPE) (
__in_opt PVOID BusContext,
__out_opt PULONG HcdiOptionFlags,
__out_opt PUSHORT PciVendorId,
__out_opt PUSHORT PciDeviceId,
__out_opt PUCHAR PciClass,
__out_opt PUCHAR PciSubClass,
__out_opt PUCHAR PciRevisionId,
__out_opt PUCHAR PciProgIf
)

From what I can gather, this is not available on a pre vista version of
usbport.sys so I don’t know if this helps you or not. Hopefully it does

Thanks, it looks promising. No problem with pre-Vista because there remote wakeup works. I have to only make workaround at Vista. BTW, I enabled traces and the remote wakeup signal from the device is recognized. OS just doesn’t complete WaitWake IRP for some reasons.

If I understand correctly, I should send IRP_MN_QUERY_INTERFACE request to get the structure with function pointers. I can check if I get version 3 and if so, I can call QueryControllerType.

You would need a blind scan since the driver wouldn’t have knowledge of
the connection topology.

When should I stop scanning? At the first failure or can there be gaps? If so what would be reasonable max values? BTW, would such driver pass WHQL tests if the function is marked obsolete? IIRC there is checks for imports.

I’ll try what Doron suggest at first, it looks less intrusive. Thanks anyway.

You need to explicitly ask for V3 (based on the interface size and the
version value in the QI). I am pretty sure there are samples on how to
get V2 (for IsHighSpeedDevice()), so you just need to adjust for v3.

Well, there can be 256 busses, 32 devices per bus, and 8 functions per
device. There certainly are gaps.

Are you talking about the PCI chipset or the USB controller chipset?
The PCI chipset is usually (always?) on PCI bus #0.

Thanks, Doron. I implemented it and it works as expected. The code which checks for high speed device is in the IsoUsb DDK sample.

You need to explicitly ask for V3 (based on the interface size and the
version value in the QI). I am pretty sure there are samples on how to
get V2 (for IsHighSpeedDevice()), so you just need to adjust for v3.

Thanks, it looks promising. No problem with pre-Vista because there
remote wakeup works. I have to only make workaround at Vista. BTW, I
enabled traces and the remote wakeup signal from the device is
recognized. OS just doesn’t complete WaitWake IRP for some reasons.

If I understand correctly, I should send IRP_MN_QUERY_INTERFACE request
to get the structure with function pointers. I can check if I get
version 3 and if so, I can call QueryControllerType.
