Hi, Wolfgang.
Your hardware is almost identical to mine, and I'm also running IT/IP 6.3.
I've dual-booted for years and ran mostly Vista Ultimate x64 until switching
to Win7 Ultimate x64 during beta and now RTM.
My motherboard has 4 onboard USB slots on the back of the case, plus headers
for several other USB connectors. I have a 4-slot hub plugged into one of
those connectors with a 3-foot cable so that I can put the hub closer to my
desktop for devices that I change often.
When I plug my desktop 6000 USB transceiver into a slot on the hub,
everything works fine - until I need to dual-boot into Vista or back to
Win7. Then the OS menu does not get my keyboard's up/down arrow signals to
select another OS. (I don't recall if <F8> works, but it probably does not.
I can't even enter the BIOS by pressing <Del>. Apparently the hub is not
recognized until Windows starts its driver.) So, I have to unplug the
transceiver from the hub and plug it into a native USB slot on the back of
the computer. Then there is no problem with reception during boot-up or -
most of the time - during normal operation. But often, when using the
back-of-the-case USB slot, the keyboard will just "go to sleep" while I'm
typing - right in the middle of a word! :>( Nothing seems to wake it up
for a minute or two - after which it continues normally for a while. During
that minute or two I try many things - swapping batteries, re-synchronizing,
banging keys - until something works; but I think that what actually works
is the time that I spend trying those things.
So I can have my choice of narcolepsy: While booting, or while typing. But
I haven't yet managed to eliminate it entirely. I've complained often, but
no relief has been forthcoming - or even promised.
Good luck! And please post back if you find a solution.
RC
