Hi

I have had a strange issue with USB HUB's for some time now, both without
and with SP1. I'm using Vista Ultimate on a DELL XPS 1210. The problem is
that devices connected to the USB HUB seems to stop working after some time.
It is seen with my: PDA (sync doesn not work), Mouse (sometimes hangs for a
second or 2), Keyboard (reppeeeeeeeats letters quite often), USB key (not
recognized). Ifi then reboot the PC it sometimes works again for a while.
Sometimes i can also cure the problem for the current failing device by
moveing it to anther port on the HUB. I have tried 3 different brands of USB
hubs, and all shows same issues. If i connect the device directly to the PC,
the device works flawlessly. As i only have 4 USB ports in the PC, that is
not a usable solution.

I have seen that isssues with Vista and USB hubs have been mentioned before,
but did not find a solution.

Anybody got an idea of how to get rid of this anoying problem?

br Lars

That would drive me nuts. Unfortunately this isn't of any help, but I'm
running two different hubs on my Vista machine and they have never, not
once, caused problems.

I'm only telling you this so you know you have some hope of fixing it :-)

Older hubs may not work right with Vista even though they did with XP.
Also, there are two general kinds of hubs. One kind provides power for the
connected devices and the other does not. Often a laptop cannot provide
sufficient power to an unpowered hub to support a lot of devices being
connected at the same time. Bottom line: use a powered hub that is
certified for Vista.
