USB Subsystem

Wikis > USB Subsystem

There are currently two USB Warpin packages that we distribute related to USB drivers, USB and USBAUDIO.

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

  • 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 some USB audio devices.
  • The USBCALLS class driver (USBRESMG) and USBCALLS.DLL to access it.
  • The USBCALLS development toolkit.

This USB package is currently an update only. The drivers you intend to update must already be installed. This package will not check for or add any HC drivers to your config.sys, and this package will not update any drivers that are not already installed.

The USBAUDIO package contains the USBAUDIO driver and the multimedia installer. This package will install the USBAUDIO driver if it is not already installed, and will just update it if it is already installed. Once the USBAUDIO driver is installed, the normal USB package 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 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.
