1. The CS-7100, CS-9100 or RS-BA1 must be the USB 3.0 compatible version to use this USB driver. About Device Driver: If you install this package, your device will be properly recognized by compatible systems, and might even benefit from new features or various bug fixes.
2. As all the hardware devices have drivers associated similarly USB devices also have it. Sometimes proper drivers do not get detected after the initial installation so reinstallation of the drivers helps resolve the issues. Let us work together to troubleshoot this problem. Follow the methods below and check if it works.

The uncommitted output transistors provide either common-emitter or emitter-follower output capability. Each device provides for push-pull or single-ended output operation, with selection by means of the output-control function. The architecture of these devices prohibits the possibility of either output being pulsed twice during push-pull. Bluetooth Software - Broadcom. It is mandatory that you specify an input and an output. So input either from a file with the -i option or the Portal with the -p option. An output must also be specified either from a file with the -o option or to the Portal with the -P option. However the input and output cannot both be the Portal. Examples editor -p -o spyro.bin.

Thesycon’s USB audio class driver TUSBAudio targets USB audio devices for professional and semi-professional use and highest quality audiophile HiFi systems. The driver supports devices which are compliant to the USB Audio 2.0 or USB Audio 1.0 device class specification. The driver provides an ASIO 2.3.1 compliant software interface and integrates with Windows as a standard WDM/DirectX compatible sound device. If the device provides MIDI features the driver exposes standard Windows MIDI ports.

To meet professional audio requirements, the audio class driver is optimized for low latency and low CPU load. Buffer depths can be adjusted by the user to optimize settings for a given computer. The driver implements a transparent (bit-perfect) playback and recording data path.

  8-channel unit can either be exposed as 7.1 or 4 x stereo playback
• bit-perfect playback and recording through WASAPI
• volume and mute control through Windows standard GUI (depending on device capabilities)
• jack sensing (depending on device capabilities)
• PCM 16 bit, 24 bit, and 32 bit sample format (depending on device capabilities)

DSD Support

• native DSD mode through ASIO (see above)

• Multiple applications can share a MIDI input port.
• Optionally, multiple applications can share a MIDI output port.

Virtual Channels Add-on

The Virtual Channels Add-on is an optional component of the TUSBAudio driver and has to be licensed additionally.

• virtual input or output channels can be defined (e.g. loopback channels)
• virtual WDM sound devices can be built from virtual channels
• arbitrary signal routing between physical and virtual channels can be configured
• routing and weights are fixed (not dynamically configurable through API)

Mixer Add-on

The Mixer Add-on is an optional component of the TUSBAudio driver and has to be licensed additionally.

• driver implements complete mixer matrix for all input and output channels
• any mixer weight can be controlled through API at runtime
• SDK included, contains sample application for mixer control
• virtual input or output channels can be defined (e.g. loopback channels)
• virtual WDM sound devices can be built from virtual channels
• application examples: monitor mix, loopback channels, channel swap, balance, etc.

Silicon Portals Input Devices Driver

• The driver will be delivered fully customized for licensee’s product.
• Customization includes USB VID/PID, file names, text strings, etc.
• Windows 10 version of the driver is signed with Microsoft Attestation signing.
• Windows 7/8 version of the driver is signed with Thesycon’s code signing certificate.
• Driver Customization Kit add-on: The Driver Customization Kit enables licensee to customize the driver by themselves.

• Wizard style user interface for interactive use
• Command line interface (silent mode) for integration into overall software setup
• Customization possible

The USB Audio 2.0 Class Driver for Windows implements the USB Audio 2.0 and 1.0 device class specification and is independent of the specific silicon and firmware solution used in a given device. As long as the hardware and firmware implement the descriptors, endpoints and requests defined in the class specification the driver should work. However, there are some requirements and assumptions as listed below.

• A device can implement a playback data path, a recording data path, or both.
• Both playback and recording path must be driven by the same sample clock source (as required by ASIO).
• An Audio 2.0 device must implement at least one clock source unit. If there is more than one clock source then a clock selector unit must be implemented as well.
• The driver supports the asynchronous, synchronous and adaptive endpoint synchronization model.
• If there is a recording path (IN endpoint) then the driver uses the incoming sample stream as clock reference to generate the outgoing stream (playback path).
• A playback-only device with an asynchronous OUT endpoint must implement a feedback endpoint.
• Optionally, a device can implement a feature unit to expose volume and mute controls.

Our software is purely designed and implemented by our team in Germany - no outsourcing. Technical support is provided directly by the developers.

Current Version: 5.0

To receive a free demo, prices or license agreement, please fill out the contact form.

The free evaluation version of the TUSBAudio driver works for an interval of 60 days without any limitation. After that evaluation period has expired, the driver stops working.

NOTE: The driver described on this page is *not for use by end users*. It will not help solve any problems you may experience with a consumer device such as a webcam, camcorder, card reader, external sound card, etc. Thesycon’s device drivers are software components intended to be used by hardware or software manufacturers to create end products.

For each USB device model an official USB vendor ID (VID) is required. Vendor IDs must be unique and will be assigned by the USB Implementers Forum (www.usb.org). Registration fees will be charged.

Thesycon owns a USB vendor ID and provides a subset of product IDs (PID) to licensees of Thesycon drivers.
