My problem is a difficult matter:
If I plug any usb-stick: It gets recognized (in systray you see: Device-name, "drive"). But NO drive letter gets assigned! If I do it manually with partition manager mmc-plugin, it still does NOT appear within the explorer! - If I right-click on the device and select "search through" (2nd in list) then the explorer opens but the drive is NOT accessible there. If I select the 1st from the list ("open"), the device OPENS in a new window, BUT: the address-bar of the explorer is EMPTY!!?? If then in this new window (with the root-contents of the usb-stick) I look at the properties, it says as location the drive letter I assigned. Within a cmd-window, I am also able to access the drive. Single left click on the systray (eject portable-media icon) still shows NO drive letter!
If I simply type the drive letter within the address bar of the windows explorer "<assigned drive letter>:\" and press enter I get the error message: "Microsoft Internet Explorer: file:///<assigned drive letter>:/" was not found. please assure that the path is correct.".
The obscurity continues: If I log off and log on again: I SEE the drive in explorer and I am able to work with it normaly. BUT if I eject the device via the acording systray-icon or by just unplugging it, I have a drive-letter-ZOMBIE ... means: If I click on it (of course) I get an error message. If I REPLUG the device, the drive does again NOT get a drive letter and the zombie-drive-letter is NOT available as free-drive-letter anymore. If think, if I reboot the zombie drive is vanishs.
I already tried to resolve this with a repair-install booting from the windows-xp cd. No change.
I already tried to remove all hidden usb-devices and drives from the devicemanager via:
SET DEVMGR_SHOW_NONPRESENT_DEVICES=1 <Enter>
Start Devmgmt.msc <Enter>
I don't want a clean reinstall from scratch, because this would mean a LOT of work installing ALL applications and their settings.
Thnx for any help and hint in advance.
