USB 3.0, the upcoming version of the universal add-on standard re-engineered for the HD era, made a small appearance at the Consumer Electronics Show (CES). It wasn't demonstrated in operation, but we did get to see what the new connectors look like. Not, alas, the optical one, we have to report, but the electrical connectors. …
Interesting, up to 6A, 24V.
IMHO, the EU should be pushing this hard, and banning wall warts. As I said in my last post, PC power supplies are much more efficient than wall warts, and they go off when the PC is turned off. The EU should mandate powered usb sockets on new desktop PCs, and forbid any USB PC peripheral, from taking power from a wall wart.
Low powered devices would use normal USB power, medium powered devices would be powered via this poweredusb standard, possibly via a powered hub to supply the power, for backward compatabllity with older PCs, and the highest powered devices (laser printers, huge monitors etc), would draw AC power from the mains and have an internal PSU. (With a legaly mandated minimum efficiency, and auto standby when the host PC powers down).
Evil: HD-DVD, USB Good: Bluray, FireWire we have a tie here people
Well, I'm only about the best more reliable most capable tech winning.
No question FireWire lost out to USB 2.0 (USB 1.0 didn't compete nor was it intended to compete with FireWire)
But Bluray did beat HD-DVD, so I guess we have a tie for Evil vs Good winning.
BTW here's what I have currently connected to my computer via FireWire and USB:
FireWire (FW400 except when indicated)
3 external hard drives drives (250GB(x2) and 500GB) (all FW800)
3 DVD burners
Portable Hard Drive (old 30GB) this is both USB and FireWire, it can be powered off of FireWire but needs a walwart when using USB.
USB (2.0 except when indicated)
2 USB hubs
keyboard (USB 1.1)
mouse (USB 1.1)
mp3 player (actually 2 one for car, one for wife)
8GB flash drive
Canon digital camera
Nikon digital camera
Scanner/printer (Canon MP830)
Wide format printer (Epson 2200)
2 USB 1.1
13 USB 2.0
RE: Parellel lines
Given all the above discussion, can anyone please explain to me why 75% of the PCs on the market still come with PS2, serial, and (fwer gads sake!) PARALLEL printer ports??!
Because people still use them! Some software makers still hav'nt moved on to USB security dongles so for some parallel is a must.
Intel got it all wrong with there new vpro boards, no PS2, Serial, Parallel or floppy. Oh, and the raid driver comes on a floppy. Nice one Intel.
wirless usb at 600mb/s (max, probably 80% of that in a good environment), is in development. I dont neccesarily think its the standard that will win out however. It will (probably) use ultra wide band, which is good for short (in the same room) transmission.
The standard its based on is ECMA though, which can indicate some funnyness.
re: poweed usb
wow I have seen thouse in all the dells at work and I never knew it was a standard!!! I thought it was some dell propirty for they external cd's yer we should push this standard.
Firewire & USB
Firewire - great for sustained data transfer for cameras and removable drives.
USB - great as a means of connecting a wide range of peripherals that don't require sustained data transfer.
All the moans about USB forget what a huge convenience USB is with external hubs when you have a huge amount of devices and limited ports on the computer. Imagine the pain involved daisy chaining firewire gadgets!
Change Plug to a ROUND plug or a Double USB Stacked back to back
I would suggest that the USB 3.0 plug change to ROUND Plug that you would not be able not to be plug in the wrong way... I am constant struggle plugging in a USB drive. ( Oh wrong way switch it around ).. Why not make it ROUND. It would be great if you could cover the connectors within a cylinder tube connector that you would push in and turn to lock. Something like a arming cylinder used to arm Genesis Device in Star Trek 2 ( see video ) http://www.youtube.com/watch?v=xbaKMXHhfhk
Or... if you want to use the same plugs.. then why not stack two of the current usb connectors not one on top of the other, but with two stacked top to top.
[| ] [| ] current usb 2.0 arranged sideway. The | is the blade in side the USB Connector
[ |] [| ] usb 3.0 would be two usb 2.0 connectors wide connector ( standardize on the spacing and position the top to top ) that would use two/double connectors/power ( in a single double usb plug ) and be smart enough ( reverse connectors/lines like current ethernet works like a cross over cable ) to figure out if both connectors are used for one USB 3.0 device or used on a single USB 2.0 device using one connector. The upside is that you could also plug in a single USB Device into it.
Not that anyone would take any advice from a BB boosting. Just a few thoughts
RE: Parellel lines
To the anonymous coward who rant about the Serial and parallel port on PCs. I am sure glad that mine got it because it is in daily use. Lots of consumer electronic devices use serial port for debuging and that is very needed for development. I had to add an additional serial card because Dell thought that routing out one port was good enough (eventhough the chipset has 2). USB to serial converter? Thanks have tried it, it sometimes work, sometimes not.
About useless port, rather complain about the bloody analogue modem connector on notebooks. Analogue modem port is like the floppy disk of networking.
About the shape of the USB plug. Actually the mini USB plugs are D shaped. I doubt there will be a mini USB 3 plug compatible with current mini USB plugs.
actuley I used one of therm recently I needed to test a phone line in the opffice and it was the only phone jack we had (all the phones are voip things)
