Usb 3.0

z.s.tar.gz · 2009-08-18 01:52:00

I was reading about it today and was wondering what the standpoint of linux with it was. Will it have to be reverse engineered like broadcom and such?

Actually someone has already worked on and created a patch for USB 3.0 support in Linux. I don't know if her patch has been merged yet but here's her article on it on her blog: http://sarah.thesharps.us/2009-06-09-13-30.cherry

Edit: I forgot to mention that Linux was officially the first OS to support USB 3.0 in the first place.

Looking at her home page:
"Greg K-H has queued the patches for 2.6.31, so Linux users should have official USB 3.0 support around September 2009."

It's a bit funny... As Anubis said, Linux is actually the first OS out there to have USB 3.0 support.

As for your comparison, it's apples and oranges - Broadcom is a hardware manufacturer, USB 3.0 is a protocol.

Thanks, that's actually interesting to know. Now I just need some hardware to go with it.:D

Unfortunatelly, I think USB 3.0 will have a slow adaption untill Windows starts to support it. OTOH, Linux being the first OS to support it may drawn the atention from devices makers.

Anyone have benchmark data? I keep hearing "HURRR it's 10x faster!" with no data to back up these claims.

Most probably most devices will be USB 3.0 compatible and work at USB 1.1 or USB 2.0 speeds until some manufacturer is bold enough to release some proper USB 3.0 device and everyone has no other option than jump on the bandwagon

The USB 3.0 spec is fully backwards compatible (2.0 and 1.1) by default. Controllers will be able to accomodate old and new connectors alike.

http://en.wikipedia.org/wiki/Universal_ … us#USB_3.0

There is no such thing as forcing users to migrate to 3.0 hardware.

Also, I am more interested in a final 802.11n spec than in crappy USB upgrades. USB has competition by FireWire and eS-ATA (high bandwidth) and bluetooth (keyboards, mice - low bandwidth), and I find all those technologies more interesting (and easier to use) than USB.

Considering that this is Intel's baby and they make hardware, my guess is that Intel is going to push this.

Asus's next mobo (P6X58) that was getting attention because of the announced usb 3.0 sockets was cancelled, someone at Asus said "there were no particularly interesting reasons" to why the mobo didn't even got to mass production.

edit: usb 2.0 still works fine.

I don't understand why they made the plug so ugly. Beyond that, USB isn't particularly exciting. It's nice to be on the top of the hardware hill for once. Suck on that Windows!

Except that it's the most wide-spread external interface ever? Just read an article on Heise a week ago about how it broke the 40-billion mark or somesuch.

Anikom15 · 2009-08-26 23:42:22

The Keyboard's the most used input device. It's no big deal. It's just the thing you use to plug stuff in.

s3kt0r · 2009-08-26 23:57:35

I still use ps2 for kbd, mouse. Usb for external hdd. As a product, it probably returns huge profits.

How is Bluetooth, wireless n, or anything else easier to use then something where all you have to do is plug it in? I guess I don't see anything being much easier to use than usb.

One of the main benefits of usb 3.0 is for flash drives since they go as fast as they can on usb 2.0. I'm sure other devices are the same. For webcams high definition will be possible. I know some webcams kinda do this already but on usb 3.0 there should be no problem. As for keyboards and mice and other devices there is no benefit.

You could install arch to a flash drive and it will boot even faster! Maybe I actually have no idea what would be limiting the speed.

Overall backing up and transferring data will go a lot faster.

USB is a shared bus, and shared buses are, well, obsolete. PCI was shared, PCI-E is dedicated. USB has a whole lot of other devices on it - this is my laptop:

Bus 005 Device 002: ID 147e:2016 Upek Biometric Touchchip/Touchstrip Fingerprint Sensor
Bus 001 Device 007: ID 044e:300d Alps Electric Co., Ltd Bluetooth Controller (ALPS/UGPZ6)
Bus 001 Device 006: ID 05ca:183a Ricoh Co., Ltd Visual Communication Camera VGP-VCC7 [R5U870]

All those devices share that same bandwidth together with whatever device you connect. Mice and keyboards don't need bandwidth, they're fine with slow connections. External HDs or optical stations do though. FireWire for example doesn't have a shared bus design, so you'll have those real 400 Mbps (or 800 Mbps), protocol overhead included of course. I think eS-ATA is the same. So while USB may be a tad more convenient to use because it's more wide-spread, that doesn't mean it's a better solution. A speed bump, as huge as it is (theoretically) will not solve those flaws.

That's cool I didn't know that. But it's still pretty fast anyways. I would be more open to another solution but it looks like usb will always be most popular. I mean if they made a fire wire flash drive or any other kind of flash drive or non usb device it would suck not being able to use it on any computer. I do like things like express card slots for laptops and what they bring to the table. Using it to add a network card is much more attractive then with a usb device sticking out of your laptop. Express card flash drives are cool but the compatability is very low.
