i have an external indidvd 8x and it doesnt read anything at all. its registered in my computer as drive f:, a dvd-r drive. it automatically installs itself but it cant read anything once i plug it into my usb port. maybe its my usb port... im using a pc card to create a usb2.0 thingy on my laptop.. its a siig brand that adds both a usb2.0 and firewire... i dont think its my pc card since i get da same error when i plug it into the firewire port... however when i go n look in my error logs... i see this:

The Logical Disk Manager Service failed while registering for device handle notifications on device \\?
\USBSTOR#CdRom&Ven_TDK&Prod _DVDRW840G&Rev_1.04#7&38e3199d &0&2B03010A076DA849&0#{53f5630 d-b6bf-11d0-94f2-00a0c91efb8b} . Win32 Error: 2.

If you have XP DELETE THE drivers for your USB controllers. Reboot then reload the Correct USB 2.0 Driver that came with your Ext. Drive. That the quickest/easiest I can think of.
