Hi,

Anybody got Presario 2197 (which has USB 1.1 built in) working with a
USB 2.0 PCMCIA card? I tried three different cards but can only get a
speed of a couple of times of USB 1.1. Even worse is that an external
hard drive (AcomData) can't be even recognized by any of the cards and
the laptop willl freeze a few seconds after.

The cards all work fine with a 3-4 year old IBM laptop. So I think this
is a problem of my Presario. I have sent my laptop to HP for service
for two times but they didn't fix it. A few days ago I called again and
they refused to service, claiming that this is a compatibility issue.

Thanks for your help.

This could be a power issue: how is the card powered, and how is the
drive powered?

Q

I tried to power the card with a 5V adaptor. Still the same thing. The
drive has a 250G capacity and is self powered.

Thanks.

supply via AC adapter?

Q

That is right.

That is right.

That is right

There was, I believe, a recent post on alt.sys.pc-clone.compaq by ben
myers, a long-time regular there, that some Compaq laptops have
non-standard PCMCIA sockets that do not supply enough power for many
card applications. You might repost this on that site.

Thanks a lot. That is great that I can get some more insider
information.
