USB Subsystem

Wikis > USB Subsystem

There are currently two Arca Noae USB WarpIn archives related to USB drivers:

  • USB stack update.
  • USBAUDIO installer/updater.

The USB stack update WarpIn archive contains updates for the full USB Subsystem. It consists of several drivers and other utilities all contained and distributed in a single Warpin update archive.

  • The UHCI, OHCI and EHCI host controller drivers and the USBD driver.
  • The USBHID, USBKBD and USBMOUSE class drivers which support generic keyboards and mice.
  • The USBPRT class driver which supports printing to generic USB printers.
  • The USBCOM class driver which supports communication with some USB serial devices.
  • The USBAUDIO class driver which supports class 1 USB audio devices.
  • The USBCALLS class driver (USBRESMG) and USBCALLS.DLL to access it.
  • The USBCALLS development toolkit.

This USB stack update WarpIn archive is only able to update an existing installation. The drivers you intend to update must already be installed. This package will not install any new host controller drivers, but in some cases it can install class drivers.

The USBAUDIO installer/updater WarpIn archive contains the USB class 1 audio driver and the multimedia installer. This archive will install the USB class 1 audio driver if it is not already installed, and will just update it if it is already installed. Once the USB class 1 audio driver is installed, the normal USB stack update WarpIn archive will also be able to update it.


Please read the USB ReadMe and the USBAUDIO ReadMe before installing and using this software.


The toolkit for building applications that use the USBCalls interface to the USB stack is available here:

Support and Submitting Tickets

Only the official Arca Noae 12.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.
