Hi, I'll show my ignorance and ask:
Do USB devices work seamlessly on Macs and PCs (with USB ports)?
Do USB mouses and USB keyboards just plug into a 800MHz 12in iBook?
(You'll see elsewhere I'm looking for a .pdf manual so I will then know
what the various "plug-holes" - ports? - are for.)
I've just got this machine and find the trackpad fiddly, similarly for
the keyboard, so I was going to plug in the keyboard and mouse to
overcome these concerns.
Can I plug in a pair of speakers (again are USB speakers universal to
Mac and PC)?

If your kernel is configured to support host-host networking over USB,
look for a network device called "usb0". Failing that, make sure it's
compiled into your kernel.

Due to the low level nature of USB, LabVIEW has no way of talking to a

The /proc/bus/usb/devices file contains an entry for this card, which I can
recognize by its vendor ID. The entry, however, shows the "driver" field
as a blank. I have an atmel driver, but installing that module doesn't
help because I don't know how to link the USB device to the driver module.

It would seem as if using a PC loaded with Linux would be an ideal way
to do some home automation: the Linux box can be dedicated to

One of the ways to interface to the real world on a PC is via a device
called the U401, a USB to 16 line controller (more info at end of

interfaceing the U401 to real-world devices using Windows. The U401 has
been used with Linux, but I don't have any application info on the web

I plugged in an USB cable from my USB scanner into my computer and

After having worked fine a couple of times it happened that my
Win2000 installation does not recognize the HP scanner anymore.
Re-Installing the scanner driver or rebooting the computer did not help.
However the scanner worked fine at other computers.
So I assume that there are some internal USB kernal driver errors of Win2000 or
changed registry settings which do not allow to call the USB device any more.

we are currently trying to use a Cypress FX2LP for audio streaming

We have already established the audio control parts (volume, mute, etc.),
and now we're trying to stream audio data to the device.
At first we're trying to make the CPU show us that data arrived, then
clear the buffers for more data.
WinXP selects the right interface, sets the sampling rate and starts to
send data, but we do not get any of it into the FX2LP. We trie
for some weeks now, all to no avail.
What we found out is that Windows sends data with Length values = 0 (this
is okay, because it's not in the USB spec for isochronous streaming),

Sounds like a non-standard format. The Micosoft USB audio driver only works
with standard formats, as defined in the USB audio class specification.
Anyway, try asking Cypress support.

For my own interest's sake I'd like to interface with my USB GPS. (note,

I've got the documentation on the driver for the device, unfortunately its

I've seen GUID structures defined which give me somewhere to put the

What can I do with this GUID? Pass it to CreateFile? How? As the filename?
Have no idea how to format it. Where do I put the GUID_DEVINTERFACE_GRMNUSB?
What is that? Some kind of Constant?

Serial to serial is possible and there is a special cable for this. Not

is a limitation of the USB standard.

laptops that have no longer serial nor parallel outputs. Can any of you
share his/her experience with a particularly bad piece of hardware and

My own interest is to connect not one sensor, but two using the serial
output (i.e. I have two sensors needing rs-232 output) I also have only
1 usb connection on that lapttop and think that on top of using a 2
rs-232/usb adapter, I will probably plug it to a usb hub because I need
to have access to other usb sensors (web cams). If you also have an
insight on the type of hub that work for this particular type of
