USB: no reaction when plugging

[Juergen Striegel]

I'm using a ALI M1541 Mainboard (ALI PCI to USB Open Host Controller). I
added the "Generic USB Input Device Support" macro, the USB user
interface and some reg-entries Andy suggested

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags
UsbFlags
IgnoreHWSerNum04710302 = REG_BINARY 1 1
GlobalDisableSerNumGen = REG_BINARY 1 1
GenericUSBDeviceString = REG_SZ "USB Device"
GenericCompositeUSBDeviceString = REG_SZ "Composite USB
Device"

But there's simply no reaction when plugging a device (flash stick, IR
Adapter, Wheel Mouse) into the USB connector. When searching for new
hardware the USB symbol appears on the tray reporting that there's a
unknown USB deive. But it soon disappears without any effects. No entry
for any unknown devices is made in the Device Manager (USB Root Hub and
the ALi PCI to USB Open Host Controller are there, of course).

The USB connection itself should work because BIOS sees the Flash Stick
and can boot from it.

Any ideas?

A few random things that you could try, if you haven't already:

- Use the "usbview" program to check that the USB config information
is being read correctly from the device.

- Have a look in setupapi.log to see what goes on when the usb
device is plugged in - this might give some clues as to what is
going wrong.

- Does it work under XP Pro SP1 running on the same hardware?

Cheers,
