Support and Submitting Tickets

Only the official Arca Noae 11.xx versions of the USB software are supported here. If you need support for a different version, please consult the documentation you received with your software for instructions on getting support.

Please read the Troubleshooting page before submitting a ticket.

Reporting bugs and requesting new features is done through the ticket system. You can view existing tickets, add comments to them and create new tickets using the corresponding buttons at the top of every page. If you want to submit a new bug or request a feature, please use the Search function first to make sure there is no ticket for the same problem already created.

  • Please enter a useful description of the actual problem in the Summary. The summary should not contain version numbers.
  • Please only submit one issue on a ticket. Do not list several issues on a single ticket.
  • Please do not post information about your system on someone else’s ticket. USB issues are complex enough that even if you have the same system and the same symptoms, your problem may not be the same. So open your own ticket — don’t post on someone else’s. If the developer thinks they are related, then the developer will link the tickets together.
  • Make sure you attach a testlog log file to your ticket when you open it.
