P4B533-E .. USB2 problem

I have just bought a digital camera (USB2 high speed comptabible), but
when I plug it in it doesn't get detected as such - just a normal (slow)
speed device. I have searched and found a few people with this problem with
this motherboard, but haven't found a solution. I have uninstalled and
redetected the USB ports, upped the USB voltage. I'm running XP SP1, and I
am using the LAN port (I read one person say it causes a conflict - others
say it doesn't).

So, any magic bullet for this problem ? Re-installing windows is not
really worth it - the extra time it takes to download pictures is still less
than that chore. TIA for any tips. I have spent an hour googling here and
there - so I covered most of the obvious.

The Cleanup procedure involves removing the USB entries in Device
Manager in Safe Mode. Windows then rediscovers the ports, and with
luck, you'll see an Enhanced entry, if there wasn't one there before.

My guess is, you've been fed the same marketing BS that some people
got with their flatbed scanners. "USB2 compatible" doesn't mean
the same thing as "USB2 data rate". Compatible means it plugs into
the same hole, not that it actually runs at the full rate. The
memory cards on a digital camera, might run in the range of less than
1MB/sec to maybe 10MB/sec, with the average camera being on the low end.
A 1MB/sec memory is quite nicely handled by USB 1.1 rates (i.e.
12Mbits/sec = 1.5MB/sec)

What you need to do is check to see if the camera actually transfers
at rates faster than 12Mbits/sec.

HTH,

You are quite right - I found a review that noted the speed - 731 kb per
second to a USB2 computer, so I'm guessing that's why it doesn't appear as a
high speed device :)

Frankly I don't care about the rate - its only 128MB flash card - I was
just concerned there was something wrong with my USB 2 ports, as with a
multi-gigabyte external hard drive I would care about transfer rates.

Stupid BS advertising on the box - boasting about USB2 transfers :(

Thanks for the right direction.
