WinTV USB - problem via USB 2 input

[Guest]

Archived from groups: rec.video.desktop (More info?)

My WinTV USB Pro (USB 1.1) plays fine through my USB 1.1 inputs in my laptop
(Windows 98SE). However, all I get via the USB 2 inputs on my PCMCIA
combo card is the WinTV program opening but no picture or sound, even though
the sound cable goes from the WinTV box direct to the mic input.

(I tried retuning it when connected via USB 2 as a last resort, but,
obviously, that didn't help.)

I dual boot (both 98SE) and it's the same on both systems even though one
has the lastest WinTV program and driver and the other has an earlier
version.

The combo card works perfectly - my other peripherals work through it
including a dvd burner, which gives much higher write speeds via the USB2
input than the laptop's USB1 input.

Obviously, this is a trivial thing;; nevertheless, the WinTV technical help
said it should work through the USB2 input. They did suggest an IRQ
conflict, but it seems that the all the USB inputs share the same IRQ (10)
and it works perfectly via the USB 1 connection. And I'm not sure that
would explain the lack of both vision and sound.

Any ideas or suggestions much appreciated.

Ok, how about a shot in the dark?

Set up a hardware profile in which the USB 2 drivers are disabled and
see if booting to that profile helps.

I no longer have any Win 98 systems to look at, but in XP Home's device
manager, the USB 2 seems to be a single driver, and USB 1 seems to have
drivers for each controller on my computer. You might have to
experiment...

HTH (but doubtful),
