USB Stick 2.0 vraag

[Verwijderd]

Ik heb een USB Stick nodig van 1GB.
Bijvoorbeeld deze http://www.twinmos.com/flash/flash_p_usb20_mobile3.htm

Volgens de documentatie werk het op USB 2.0 (vanaf 512MB werken de meesten daarmee)

Nu wil ik mijn stick in oudere machines gebruiken waar geen USB 2.0 op zit.
Iemand enig idee hoe dat zal gaan werken?

Het zal sowieso trager gaan, maar werkt het dan gewoon zoals het hoort?

Dat werkt dan op max speed van USB 1.0 / 1.1 Maar de werking blijft exact het zelfde.

Dat zal dan gewoon op de snelheid van USB 1 werken, maar het werkt wel.

Mijn dank is groot heren!

dat is volgens mij basic stoff

Let er wel op dat USB 2 ook in 2 snelheden bestaat.
Full speed en High speed. Full speed is 12mbs (oftewel oude USB 1) en High Speed is 480mbps (oftewel de maximale snelheid van USB 2) Beidde worden dus tegenwoordig usb 2 genoemd.
Tevens dient je pc ook USB 2 drivers te hebben. Anders zal hij nog steeds maar op 12mbps werken.
XP geeft daar overigens wel een melding over.

Aan de hand van Google had je dit in no-time kunnen vinden.
Bijvoorbeeld deze pagina (1^e hit):

How fast is USB 2.0?
USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps. Originally, USB 2.0 was intended to go only as fast as 240Mbps, but then, USB 2.0 Promoter Group increased the speed to 480Mbps in October 1999.

How will consumers benefit from USB 2.0?
With speed 40 times more than that of USB 1.1, USB 2.0 broaden the range of external peripherals that can be used on a computer. Even with multiple high-speed peripherals connected to a USB 2.0 bus, the system will less likely to hit the bandwidth bottleneck. The new specification also inherits the current USB�s Plug and Play and hot-swapping capability as well as providing backward compatibility for USB 1.1 hardware, allowing existing user base to upgrade seamlessly.

Do USB 2.0 & USB 1.1 hardware work interchangeably?
You may have heard that USB 2.0 is "backward-compatible" with USB 1.0/1.1 (Full-Speed USB). While that's true, USB 1.1 is also forward-compatible with USB 2.0. Whenever a system has USB 2.0 ports, you'll find the "Enhanced" USB controller in Device Manager, but you will also find two other USB controllers. These two to mantain backward compatibility to USB 1.1 devices. Each USB 2.0 host actually has 3 chips onboard. The USB controller routes signals to the correct controller chip depending on how a device is recognized. Where a device is physically plugged in has no bearing on how it is routed. All ports on a USB 2.0 motherboard can host any USB devices at all as long as the system and devices are healthy.

The vast majority of USB 2.0 devices will work on older PCs and Macs. None should flat-out fail unless there are other issues with the system. Hi-Speed USB devices will revert to Full-Speed operation when connected this way. Understand that Hi-Speed is at least ten times faster than Full-Speed in actual operation, so the speed difference is quite noticeable - unless you have never experienced Hi-Speed, of course.

When it comes to USB hub compatibility between USB 2.0 and USB 1.1, here some facts:

• A powered hub is always preferable to unpowered.
• USB hub ports are not as capable or flexible as real PC ports so it's best not to expect the world of them.
• USB 1.1 (obsolete) hubs will work fine on USB 2.0 ports, but they cannot utilize USB 2.0 capabilities. They will default to slower speeds.
• Hi-Speed and Full/Low-Speed USB devices can coexist nicely on USB 2.0 hubs. Connecting such a hub to a USB 2.0 port is recommended.
• USB 2.0 hubs can be used on older USB 1.1 computers.
• Although it is said that you can "cascade" up to 4 hubs, problems may start to arise after two hubs, it's best to minimize hub usage if possible.
• Many USB devices don't work well on hubs. Cameras, scanners and especially USB drives are known to have problems with hub connectivity.
• Remember that "active USB extensions" are really just one-port hubs.

As you can see, there are very few issues (if any) to be concerned about when mixing USB types. If the system and devices are healthy, it should be a "no-brainer" to connect any USB device - provided that you follow manufacturer?s instructions.

Vooral de stukken over backwards compatibility zijn voor jou erg interessant

Oh, welkom op GoT trouwens
