USBDLM is a Windows service that gives control over Window's drive letter assignment for USB drives. Running as service makes it independent of the logged on user's privileges, so there is no need to give the users the privilege to change drive letters.
It automatically solves conflicts between USB drives and network or subst drives of the currently logged on user.
Furthermore you can define new default letters for USB drives and much more.
* Bugfix: Sicce V4.5 USB floppy drives got a high letter assigned instead of keeping them at A: or B:
* Bugfix: Since V4.5.3 USBDLM changed the Windows timer resolution from 10 or 15 ms to 1 ms - the result might be a slighly higher power consumption of the CPU
