We just released a new ProtectUSB version, which makes ProtectUSB the clearly leading solution for high volume PC based USB duplication.
Starting today, you can use your PC to write to 100+ USB sticks in parallel using regular USB hubs.
With ProtectUSB's physical layout feature, you can map every physical hub position into ProtectUSB's physical layout view and instantly observe the process and status of every connected port/stick.
ProtectUSB is available as a free update as of now. On starting your old version, the new version will automatically be offered for download. Existing licenses work also with the new version.
