Usb 2.0 hub - how to test it is working at the correct speed

I have a usb 2.0 pci card and have just purchased a peak powered 4 port usb 2.0 high speed hub. i keep getting a message saying my device will work faster if i switch to 2.0.

the pc engineer who sold me the hub has told me it is working properly. how can i check this?

he also said that i might be getting this message erroneously if i don't connect everything in the right order. but apart from telling me to check that it is plugged in he didn't give any details of how to connect properly - just that i need to do it all in the right order.

can you help please? i don't want to pay for something that isn't doing the job. thank you.

Get a USB Storage device - if you can copy a file of about 100mb in under 10-20 seconds, then chances are it's USB2. USB2.0 is 480mbps where as 1.1 is 12mpbs (or something tiny in comparison)......

This error doesn't mean that there is anything wrong with the device. If a device says it is USB 2.0, it usually is. This means that the USB port you plugged it into or your computer altogether doesn't support USB 2.0.

Ml350 g5

Most current high-performance graphics cards (GPUs) are PCI Express (PCIe) cards. The others use the "legacy" standard known as AGP.

ML350 G5 has PCIe slots, but they are x4 or at most x8 variety: most high-performance GPUs require a PCIe x16 slot. Of course, PCIe cards are supposed to work with lower-bandwidth slots too, but that limits the performance of the card. I would not expect high-performance GPU manufacturers to do much testing with limited-performance configurations, so you would easily find yourself in the land of "unsupported".

PCI-X is a faster/wider version of PCI for servers: I don't know of any common high-performance graphics card that would use a PCI-X slot.

PCI-X is backwards compatible with plain old PCI, but I would not call any PCI graphics card "high performance" today.

Most high-performance GPUs also require more current than a standard PCIe slot can supply. That necessitates an extra power feed from the PSU to the card, but such a power feed is not often available in server-style machines.

Trying to convert a rack-mount server into a graphics monster machine is like trying to adapt a Formula-1 car for a gravel-road rally: different roles call for different designs.

Module: x3200m2 type:4368 i1s server how many lan (ethernet) ports are available for usage

Number of all ports available: Six USB; Ethernet,two serial,parallel and Video.
One x8 high-speed PCI-E adapter slot offers investment protection by supporting high-performance adapters, such as Ethernet, Fibre Channel and InfiniBand cards, none of which will run in older conventional PCI slots.
The x3200 M2 includes one integrated Broadcom 5722 Gigabit Ethernet controller for up to 10X higher maximum throughput than a 10/100 Ethernet controller. In addition, the 5722 supports IPMI-over-LAN.

I have one bad usb port

If you need multiple USB ports, go onto ebay and find a 3.3v PCI usb card. The large PCIX slots in the server are PCI compatible and will accept a 3.3v pci card. (It just doesnt fill the entire socket), or you will notice to the bottom of the mainboard there is ONE 5v pci slot, you can get a 5v PCI USB cotroller and stick it in there.

Either way, you have more USB sockets. As the mainboard ones are built in, if its broken, you either need to get a new mainboard (not cheap), or get a cheap PCI USB card.

(Note if using ESX, ESX 3.5 and below do not recognise USB ports anyway).

I have one myself and have done as mentioned.

HP DL380 no display on screen

does the server power on?
When i purchased my first DL380 i had a simular issue, as it turns out the datacenter i had purchased the server from, had installed a ILO replica type card. if you have the same card installed (it will have a ethernet port, power port, and video port) , this can be causing the issue, also, the card will be located in the PCI-X Slot.

Buy a expansion usb card and also sound card to a near computer shop in your place. If you have the items then follow this steps:

1. Open your computer casing where the motherboard lies in.
2. Look for any vacant pci slot in the motherboard
3. Plug in all the cards properly(usb card and sound card)
4. Close the computer case.
5. Startup your computer, be sure you connect all the cords back properly before starting.
6. Install all the drivers provided in the CD by the product purchase.
7. Once all complete,your done!..

Hope this could help you..thanks..

Which USB card will work.

Almost ANY that list Windows XP on the side of the box.

Here is one for $9 that was rated 5/5 by 197 people.

Anyways, USB 2.0 has been out for many years, is a standard on all computers, and is 400x faster than USB 1.0.

Either way, I recommend you goto, as all of their products, including their PCI USB expansion cards, have honest reviews from users that purchased them. I always read the reviews there before purchasing. And I would think 80% of the reviewers there even, have WinXP Pro SP2, however they will even state it alot of times, in addition to the Specifications page listing it.

Either way, very easy upgrade, have fun.

Usb modems will not work see's modem but will not complete driver install. Even if you manually update. Tried 2 modem's

check to make sure that your USB ports are working properly. Best thing is to hook up a usb mouse or usb keyboard.

if it recognizes those and installs the drivers properly then you know your USB ports are fine, at this point you know that its got to be something with the modems, either they are not compatible or the modems are bad.

Try a brand new usb modem and make sure whatever type of usb port that the modem requires is the type of usb ports you havve on your server.

My Dell PowerEdge 2500 has 2 configurable com ports which are setup as Com1 IRQ-4, and Com2 IRQ-3. My problem is that everything seems to say that they are there and active, but my software only can talk...

That "in-op" COM port is in fact, probably defective. Had many cases where 1 works/1 doesn't. Buy a cheap, PCI COM port board, install the software, and plug away!
