USB Flash Drive detected but not shown in Windows Explorer

I am using Compaq Presario 1200, running on Windows ME.
I encounter problem with my Apacer USB Flash Drive. Previously it was working properly. When I plug in the USB Flash Drive, a "Removable Disk"  will be listed under the My Computer in Windows Explorer.
But lately, when I plug in the USB Flash Drive, it didn't show up in the Windows Explorer. So I check the Device Manager. I notice a "?" on the USB Mass Storage Device icon. I remove the USB Mass Storage Device and restart the computer. Plug in the USB Flash Disk again and face the same problem.
Then I use the CD comes with the USB Flash Disk and update the driver. After updating the driver, Device Manager shows that the USB Mass Storage Device is detected and no error reported. But the Windows Explorer still didn't show the Removable Disk.
Later I realize that my Notebook supports USB 1.1 but the USB Flash Disk is USB 2.0. I guess the USB Flash Disk is supporting USB 1.1 because it works in the first place.
How can I get the USB Flash Disk to work again?
