Yeah, it's a fake from Sony. I have 3 USB 2.0 Ports on my Laptop. But the reality is : Only on of them is an USB 2.0 Port.

Yeah,

The other both are only connected with the USB 2.0 Port (like a Hub)
I think your desktop VAIO has the same ****, tikka.

I know the front ones are USB2, as I plugged in my Maxtor USB2 drive.

check this with SiSoftSandra or Everest Home Edition. Then you see which are USB 2.0 ports.

Or start the Systeminformation tool and make a look by "components", "USB".

USB\ROOT_HUB20 = USB2.0
USB\ROOT_HUB = USB

The USB\ROOT_HUB20 use an extended Host Controller and the USB\ROOT_HUB use an universal Host Controller.

The extended Host Controller has his own power supply and the universal Controller get his energy from the extended Controller.
That's the same like a USB Hub which you use, if you not have enough USB Ports.

max 500mA on the extended Controller
max 100mA on the universal Controller

(out of topic)

I've noticed the a MemoryStickPro isn't faster as a MemoryStick.

True, If you write data on the MemoryStick. The MemoryStickPro is faster.
But if you read data, both have the same speed. LOL

I think it's because it's only USB 1.1

I have a build in MemoryStick slot in my VAIO.

If I formating my 256MB MSPro Duo, I need approx 3-4 seconds. My 64MB MS needs approx 10seconds.

But if I copy a file (same size) from the Stick to the HD, both Sticks needs the same time.

Mmmh, strange:smileycool:

Mine is built in too, but it's a USB1.1 interface.

Re: usb speed

seb21__ — Tue, 15 Mar 2005 21:04:14 GMT

Mmmh?

A MS use a USB interface? I don't knew this.
But USB 1.1 has only theoretically 11MB/s. LOL

Re: usb speed

kee-lo_ — Tue, 15 Mar 2005 21:37:21 GMT

Yeah it's a USB1.1 device

Re: usb speed

seb21__ — Tue, 15 Mar 2005 21:47:33 GMT

mmh, then is a MemoryStick not really more as a USBStick!

Sony, you surprise me every day.

My Devices Manager said : "Sony Memory Stick Controller"

But I find it between my Floppy and my DVD drive.

I am pretty fed up and annoyed at Sony's cheapness. I also only have one working USB 2.0 port. I am going to buy a Belkin USB 2.0 PCMCIA card to rectify this.

Don't Sony realise that USB 2.0 is backwards compatible with USB 1.1 and they foot the in themselves shoot? Why put two or three USB 1.1 ports on a laptop and only one USB 2.0 port?!

Here is the Device Manager screenshot.

Offtopic lol but the MemoryStick device on my PC is actually part of the PCMCIA bus and is controlled by a Texas Instruments PCMCIA FlashMedia Controller unit. Mine is pretty fast lol.

Here is what Device Manager says about the Memory Stick...

Lol probably didn't help much...

ROFL

Its not a screenshot, but look here

+ Laufwerke
+ Mäuse und andere Zeigegeräte
- Memory Stick controllers
Sony Memory Stick controller (WB)
+ Modem

I have the feeling, Sony has experimented a little bit. LOL

Why put two or three USB 1.1 ports on a laptop and only one USB 2.0 port?!

I think that is good question for the e-support!:smileygrin: :smileygrin:
Particularly, if I look in the manual of my laptop. I see 3 USB2.0 Ports. I think Sony needs some explanations for us.:smileycool:

Re: usb speed

jammold — Wed, 16 Mar 2005 15:16:53 GMT

Lol my PCMCIA port will always be used now as I will get that Belkin USB2.0 CardBus Card.

Lol I guess its Sony being VERY cheap!:smileylaugh:
