We were kicking around some ideas today for low-performance embedded systems
for quick and dirty solutions to simple tasks. We often throw a BasicX
controller (http://www.basicx.com/) at such problems, which is fine until
we need to communicate with the user; adding keypads, LCD displays, etc. is
a bit of a PITA.
So we started talking USB microcontrollers. Once you have a USB port, using
USB keyboards, mice, 10-key keypads, etc. for input is a no brainer, but what
of the display? A quick web search didn't turn up any obvious candidates.
Then someone came up with the idea of using a U...Ethernet over usb possible between usb host and usb client?

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

The SGI320 is too old for USB2. It has USB1 ports, which are not fully

Better get an USB or USB2 PCI card...

Serial to serial is possible and there is a special cable for this. Not
sure how to order it from HP though. USB to USB is not possible - this
is a limitation of the USB standard.

but I don't really know if my pc has usb2.
When I go to 'Device Manager' on my laptop or pc, I see nothing that tells

Is there a way (a tool or so) to detect if I have usb2 on my pc?
I already tried AIDA, but I can't find it.

Is it true that one MUST use ONLY the EXACT USB charger that comes
with their cell phone? Are USB chargers really not interchangable?
The T-Mobile store told me I could only use their T-Mobile charger for
my new USB based cellphone. After showing me the charger for the
Motorola V195 which is 5.9 volts 375ma, they then opened a desk drawer
and handed me three melted USB chargers, one at 5.0 volts, 750ma;
another at 5.0 volts, 550 ma, and yet another at 5.2 volts 450 ma.
Can we swap these supposedly USB chargers or not?

to accomplish this and really, really don't want to trash the print server.
Any help would be greatly appreciated.

Vendor site or product packaging.
If what you're really asking is whether a device is capable of 480Mbps
or only 12 (or 1.5) I supposed you could plug it into a USB 2 port and
look at System Profiler. Each attached device will have a "speed" entry

to prove that s...USB
