Appears so. Ref. http://en.wikipedia.org/wiki/Secure_Digital
The system mentioned in the original message is at home.
Here at work is another machine, with an unbranded similar
adapter, running Wheezy.

With both a CF card and the NexxTech SDHC in the adapter, plug
the USB cable and this is available.

fdisk -l shows the hdd but no mention of the SD or the CF flash devices.

A 512 MB CF card in the multi-slot adapter is not accessible.
If the same CF is in a mini-adapter which is then plugged into
the USB socket on the front of the multi-slot adapter, then
the CF is readable. So the USB hub in multi-slot adapter
works to this extent at least.
An old 256 MB Kingston USB stick shows up as a device in PCManFM.
Attempting to mount it gives a dialogue with "Not Authorized".
The same happens when this stick is plugged in any other USB socket
on the machine. fdisk -l reports it and I've had it working before.
The failure of PCManFM appears to an independent problem.
That's all I have at present; the 4 GB SDHC, the 512 MB CF and
the 256 MB USB stick.

Not at hand.

Yes; first systematic attempt at use.
> ... did it work for you before with this sdhc card ...
Received the SDHC card recently and this is the initial
trial. With the card in the XO-1.5 running custom Fedora
with Gnome, no problem is evident.
> ... on another computer/operating system?
Haven't tried either this multi-slot adapter or the one
at home anywhere but the machines where they are installed.
Either adapter can be plugged into a USB socket on the XO-1.5
when there is time.
The leaflet with the AtechFlash adapter lists SD but not
SDHC. Firmware upgrade, as mentioned in
http://en.wikipedia.org/wiki/Secure_Digital#SDHC ,
is not mentioned in the leaflet and probably not possible for such a
low end adapter. Seems advisable to purchase an inexpensive
adapter for SDHC before wasting more time with obsolete hardware.
Thanks for the reply, ... Peter E.
