USBUHCD.SYS problem

Description

I have 3 UHCI and one EHCI devices (and drivers installed) on a VIA VT8237 chipset laptop with a mobile AMD Athlon 64 3200+ CPU running eCS 2.0 with UNI kernel and ACPI.PSD /Q.

With the original IBM USB drivers loaded, only the EHCI shows up in the hardware manager. USB 2 devices are recognized, USB 1.1 devices are not recognized when plugged in.

If I use the USBUHCD2.SYS drivers instead of USBUHCD.SYS for the USB 1.1 devices, then UHCI shows up in the hardware manager (along with EHCI) and all USB devices attached are recognized.

Up to version usbxhcd6 of the Netlabs drivers the behavior is exactly the same as the original IBM drivers.

Version usbxhcd7 now shows the UHCI devices in the hardware manager, but USB 1.1 devices are not recognized when plugged in (USB 2 devices are).

This looks like it is related to ACPI. With the latest test version (PollingFullOnly) I can use all of the usbxhcd7 drivers with no trouble.
