In order to connect to an external 2.5 harddisk with USB, I have tried three different USB 2.0 PCMCIA (Cardbus) cards (Belkin, Dynex and Zonet) on my Compaq Presario 2197 (AMD Athlon XP 2800). The cards can all be recognized, but only on the Zonet card the hard drive is recognized. Even so, the speed is very slow. Transfering a file of 1GB will take about 25-27 minutes. I have also tried an Acomdata external harddrive, which works great with an IBM laptop, and see the same thing. BTW, the time for transfering a 1GB file on the IBM is about 6-7 minutes. It is not as quick as a built-in USB 2.0 but still far better than the speed I got on Compaq Presario.
I am using Windows XP (SP2). It happens even on a clean installation. I have a 5v power adaptor but it doesn't help.
All the three cards work (harddrives can be recognized with a problem) on the IBM laptop.
Can anybody help? Is this a problem with AMD? or Compaq?
It sounds like the "external 2.5 harddisk with USB" only supports USB 1.x to me. I have some flash drives that only work at USB 1.1 speeds. They have to state USB2, or the device won't operate at 480Mbps.
Just for reference, my USB2 external HD transfers just under 1GB per minute.
Cheers!

I'd suggest checking the Universal Serial Bus Controllers section in the Device Manager. You should see at least one Enhanced Host Controller entry properly configured if you expect to get high-speed operation at the interface.

Indeed. Besides the "Enhanced Host Controller" device, it should (AFAIK) also list a "USB 2.0 Host Controller" device and a "USB 2.0 Root Hub Device" device. Also make sure that your *disk* is listed in the *right* (i.e. 2.0) device tree, not in another USB device tree which does not have "2.0" devices in them. That is what happened on my (OmniBook 6200) notebook, which has a built-in 1.1 interface and a plugin (Sitecom) 2.0 interface. My external disk kept using the 1.1 tree/devices/drivers, even while it was plugged in on the 2.0 interface, and, like yours, was slow, i.e. apparently working at 1.1 speed. I had to force-remove the wrong devices and force-install the drivers which came with the USB 2.0 card, to get things right.

I hope this helps.
Interesting Frank! Did this happen under Windows XP?
Cheers!

I forgot to mention that for the Belkin and Dynex PCMCIA cards, after I plug the Acomdata External HD into the USB ports on the cards, Windows would sometimes recognize the HD for a short moment, and then went frozen. These two cards have NEC chipsets and the ZoneNet card has a VIA chipset, I later noticed.
I will try to check whether my external HD & DVD-RW are installed to the right USB 2.0 tree.
Thanks everybody for your help.

I had this problem (freezing when connecting hard-disk) when my (Sitecom) USB 2.0 'PCMCIA' card used the driver whichs came with XP instead of the drivers which came with the card. After force-installing (XP didn't install the drivers on the Sitecom CD, even when pointed to it) the drivers which came with the card, this freeze problem was gone. So check (Properties -> Driver -> Driver Details...) *which* drivers are installed for the devices listed in the 2.0 device tree. If it says "Provider: Microsoft ...", then you probably have the wrong drivers.
I have installed the driver from VIA for my ZoneNet card and it is still the same thing. Right-clicked on "VIA USB2.0 Enhanced Host Controller" in the Universal Serial Bus controllers tree in Device Manager, and then Properties->Driver->Driver Details, I didn't see a tree but a list of files such as:
C:\WINDOWS\system32\drivers\usbehci.sys C:\WINDOWS\system32\drivers\usbhub.sys C:\WINDOWS\system32\dirvers\usbport.sys C:\WINDOWS\system32\Drivers\vulfnth.sys (Provider: VIA Technologies, INc) C:\WINDOWS\system32\hccoin.dll C:\WINDOWS\system32\usbui.dll
Only the file vulfnth.sys is from VIA, others are from Microsoft.
So I didn't find a USB 2.0 tree. I am wondering how I can get the tree.

With "tree", I mean the *device* tree, not a *drivers* tree.
For example my USB 2.0 looks like this in the Device Manager, after I open the "Universal Serial Bus controllers" tree by clicking on the "+" icon in front of it:
- \ -> Universal Serial Bus controllers | | -> USB 2.0 Host Controller | | -> USB 2.0 Root Hub Device
For *each* of these (in my case two) devices, you can do Properties -> Driver -> Driver Details. In my case *all* drivers/files listed are not by Microsoft (but by OWC, OrangeWare Coporation).

I had exactly these driver/file names (except of course for vulfnth.sys) when I still had the wrong drivers! So I again advise you to *force-install* the drivers which came with the card.
Force-install can be difficult, because often XP thinks it knows better and still installs the Microsoft stuff. What worked for me is this procedure (note that the *names* of the devices/drivers/files/ directories may/will be different for you):
[Start quote:] Following procedure worked to install the "USB 2.0 Host Controller" and "USB 2.0 Root Hub Device" devices with the OWC drivers: Control Panel -> System -> Hardware -> Device Manager -> "NEC PCI to USB Enhanced Host Controller (B1)" -> Driver -> Update Driver... -> Welcome to the Hardware Update Wizard -> * Install from a list or specific location (Advanced) -> Next -> * Don't search. I will choose the driver to install. -> Next -> in the "Model" list, the following are displayed: NEC PCI to USB Enhanced Open Host Controller (B1) Standard Enhanced PCI to USB Open Host Controller USB 2.0 Host Controller select "USB 2.0 Host Controller" and Have Disk... and set "Copy manufacturer's file from:" to the C:\Sitecom\Drivers\USB 2.0 directory. -> Next This will install the "USB 2.0 Host Controller" device (with OWC drivers/software cbuninst.exe, ousb2hub.sys and ousbehci.sys). After that, the "Welcome to the Found New Hardware Wizard" (note "New") will be started, saying "The wizard helps you install software for: USB 2.0 Root Hub Device" -> * Install from a list or specific location (Advanced) -> Next -> * Don't search. I will choose the driver to install. -> Next -> in the "Model" list, the following is displayed: USB 2.0 Root Hub Device select "USB 2.0 Root Hub Device" and Have Disk... and set "Copy manufacturer's file from:" to the C:\Sitecom\Drivers\USB 2.0 directory -> Next This will install the "USB 2.0 Root Hub Device" device (with OWC driver ousb2hub.sys). [End quote.]
The key items are selecting "Don't search. I will choose the driver to install.", choosing the right device names from the "Model" list and directing XP to the directory which contains the desired drivers. If you fail any of these, XP will know 'better' and install the Microsoft stuff.
