Windows XP doesn't supply all needed drivers for such a laptop. Call the vendor and get a DRIVER CD to finish the install of XP.
Just put a fresh install of Win XP Pro (SP1, 2002 Version) on the above mentioned laptop (AMD Athlon XP-M 2400+, 256 MB RAM, 30 GB HD), which is brand new.
I have tried connecting the Devo DD-200P external hard drive to each of the 4 USB ports on the laptop, but without success. XP doesn't acknowledge the presence of the drive, as you'd expect. The power light on the drive comes on and the motor gives a repeating on/off whining, very quietly.
The drive works correctly on a desktop with exactly the same OS, also it works on another laptop with XP Home. Also, I've tried a USB mouse on the IFriend without problems.
I've tried to search for the hardware manually without success. I've made sure the USB settings in the BIOS are correct, everything seems to fine. The drive jusst refuses to show up. The laptop is working off mains so I can't see a power problem.
Any help with this would be greatly appreciated!
