I was so impressed with the speed of 3.0 with my external drive.
I hope the new Olympus camera later this year has, at least, a USB 3 capability.
It would make teathered shooting, with a wireless adaptor perhaps, a very effective capability.
I also expect that new printers will have (at least existing type of) USB3.0 and after reading about Canon's new printers at DPNow, I wanted to know if they have USB3.0. I just could not find any information about it but found this information about new type of USB3.0 instead.
I wonder if printer manufacturers think that wireless LAN is more beneficial to printing and that's the main reason for neglecting USB3.0 for a long time. The existing type of USB3.0 was introduced in 2008. I determined that time that my next printer should have USB3.0. So am continuously using my beloved more than 10 year-old printer.
I have an add-on USB 3.0 interface card installed in my desktop PC but after updating the motherboard BIOS it has stopped working
Surely the enhanced USB 3.0 will be backwards compatible?

Yes, the press release says the new type is backward compatible. Actually other news suggest that it is a counter proposal against Thunderbolt, another idea of faster data processing and more complicated in a sense. The new USB3.0 is just simple.
When I plug certain things into either my desktop or laptop, I get that message saying I should plug it into a USB 3 port. However, when I look in my Device manager it lists them as USB 3 ports. Strange.
Just because cliches are cliches does not make them wrong. I do like walking in the rain.
How much more expensive is USB3 over USB2? I only ask because I'm seeing modern computers/laptops which come with 'x' number of USB ports, only one of which is USB3. If USB3 is backwards-compatible, why wouldn't they *all* be USB3 ports?
I did buy a USB3 memory stick just recently, so that I had something USB3 to try out. It's a bit false anyway, because USB sticks are notoriously slow and could probably be faster even at USB2 speeds (for instance, why do external hard drives transfer data at 35MB/s over USB2 while a standard memory stick crawls at 5MB/s?).
Reading up on them, some memory sticks listed as "USB3" aren't really doing much better than your external hard drive at 25-35MB/s anyway (which is surely what they should be doing over USB2?). Only certain specific USB3 memory sticks go any faster. Not all USB3 devices are equal, it seems. Even those faster USB3 memory sticks aren't going anywhere near 5Gb/s.
All of these claims of 5Gb/s+.... what devices are likely to take advantage of such speeds? Printers can only print so fast. Hard drives can only spin so fast. What is likely to use the new 10Gb/s to its maximum advantage?
out of the three means that connect between PC body and external devices such as HDD, existing USB3.0 is slightly faster than e-SATA and much faster than IEE1394. The last one is seemingly fading out these days.
The speed of the connecting cables/methods looks like the bottle neck for us to enjoy much faster processing speed.
The USB3.0 connector: the male side is same as the USB2.0 or USB1.1 but the female side looks a bit thicker than the predecessors. Conpatibility does not necessary mean that all the connector designs are same. So USB3.0 connector occupies more space (thickness) than older types.
It looks to me that this is a small obstacle for having more USB3.0 in ultrabook or tablettes. USB3.0 ports are however increasing. I went to a shop yesterday and found that many notebooks now have something like 1xUSB2.0 and 3xUSB3.0. So it's slow but surely changing. I have no idea about the cost diiference which I just guess marginal and it won't be the reason of late adoption.

That's something that's changing, then, because many laptops I looked at just two months ago had just 1xUSB3.0 port and 2xUSB2.0 ports. I Googled to see if I could find out why, and the best I've come up with so far is that some processor/chipsets from Intel didn't have USB3.0 support built-in as standard (Sandy Bridge, for instance) and, to have USB3.0 required an extra USB3.0 card. The more separate USB3.0 ports, the more cards, so in devices where space is a premium (like laptops), only one card is used - the other USB2.0 ports are supported directly.
Another reason I found was that Windows 7 apparently didn't have native drivers for USB3.0, so if you ended up with a crash that necessitated a completely fresh reinstall of Windows 7, it wouldn't recognise any keyboard/mouse plugged into a USB3.0 port.
So the reason for hanging on to USB2.0 seems to be for reasons of legacy support - something that will doubtless change over the next several months, particularly with newer processors and with new PCs/laptops now coming with Windows 8.
My new Belkin USB 3 card has its own internal power supply in addition to taking power from the mother board, so presumably it provides for more power hungry devices to be used as well as the higher speeds.
Funny how I still find myself setting everything going, then leaving it to make a cuppa. Most times it's now finished by the time I get back.
