Since 98SE introduced ACPI, I bet that is a possible problem. You can Google how to disable ACPI in 98SE and see if it helps.
Why would ACPI cause a problem?
Some motherboards had flawed ACPI implementations that caused strange problems and instability. It has been awhile since I've run into it though. ACPI usually works ok. 98SE will actually detect many problematic BIOSs and switch to APM mode during initial setup.
Actually some USB2.0 cards don't like to work in an ACPI-less environment (Because the WDM nature of the USB drivers themselves, very important if you are using some USB2.0 pack made with Winxp files on it). So keep that in account.
As rule of gold... Old NEC usb2 chipsets can wristband certain legacy limitations of older configurations. Them can work in old style interrupt systems (have the legacy interrupt pin... but them will eat 2 or 3 irqs, so take that in account), and in ACPI-less environments. VIA ones don't. Them require MSI interrupts, and sometimes will work acpiless, or not... depends in driver configuration, and if you are using "packs" for generic device support.
