PCMCI - USB 2.0 & USB 2.0 external hard
Dear, Sirs!
I have the problem with External Case for 3.5" hard disks using USB 2.0 (model Chronos HD-337-U2). I have no USB 2.0 in my laptop (Compaq Presario 2700 EA) only USB, so I had to buy PCMCI - USB 2.0 card model: UB 200 from ARGOCY (www.argocy.nl). PCMCI drivers were installed by me as described in users manual, i.e. after installation I had upgraded drivers for USB 2.0 Root Hub device & Card Bus to USB 2.0 Enhanced Host Controller. When I was using External Case via USB 1.1 hard drive was visible and I could read & write any files on it, after installation PCMCI - USB 2.0 card and after connection External Case via USB 2.0 I had encontered the problem my PC asking the hard (red LED is lighting on the External Case, there is two LEDs on case - red and green), but then some frizing with RED LED and External Storage divice disapeared from dialog box for safety removing any external divices (in the right low corner of descktop), and from "My computer". After restarting the computer files or folders wich were tried to be accessed lost. After some such actions after rebooting I found that all my external hard (120 Gb) was not formated and all info was lost. Please help me to dicide my problem. Thanks in advance!
After installation of all drivers as described in manual I have following USB controllers in Device manager:
CardBus to USB 2.0 Enhanced Host controller
Nec PCI to USB Open Host Controller
Nec PCI to USB Open Host Controller
Standard Universal PCI to USB Host controller
Standard Universal PCI to USB Host controller

If I want to connect external mobile rack with USB 2.0 interface it's not be recognised by operational System.
Please help me to decide the problem.
After system restoring and istalling drivers again system found Hi speed storage, but could not install correctly it, and gave the message that device will not work properly.
