| TUSB2046B
| Texas Instruments
| 4-Port Hub for USB w/Optional Serial EEPROM Interface
|}

Part TUSB2046B has the following errata published by the Manufacturer (Ref https://www.ti.com/lit/pdf/sllz051). This is handled by the XDK software driver:

TI has found that the TUSB2046B (also TUSB2077A and TUSB2036) has a slight violation in the manner that it determines the intended speed of an attached downstream device.

By the intent of the USB specification (shown in Figure 7-19), the speed should be determined by sampling the DP or DM line following a 100ms debounce interval after either signal (DP or DM) first crosses the VIH threshold. The TUSB2046B (TUSB2077A, TUSB2036) actually samples the speed at the first VIH crossing and latches this value. This issue has only been observed recently with newer devices that either drive DM high or show excessive ringing during the initial connection, hence causing the speed detection to be seen as slow speed by the TUSB2046B (TUSB2077A, TUSB2036). Note that this device is used extensively in the USB 1.1 Gold tree suite, and this issue was never revealed, further pointing to the fact that some newer devices have less control on DM than previous devices, although this is allowed by the USB specification. TI has no planned fix in the pipeline but wants users to be aware of this issue, which can easily be avoided by guaranteeing that DP be asserted high before DM. In the event that a false low-speed detection is observed, the situation can be resolved by performing a CLEAR_PORT_FEATURE(PORT_ENABLE) followed by a RESET_PORT in the software driver, assuming both DP and DM are now stable.

Xbox Cam (for Video Chat)

2023-10-26T03:44:46Z

Harcroft: Chipset and USB descriptor info added.

== Videochat - Xbox Cam ==
Xbox Video Chat was released June 2004 in Japan and is a Xbox live enabled/required video chat program with a camera called "Xbox Video Camera" that allowed users to voice and video chat with fellow Xbox Video Chat users. An active Xbox Live subscription was required. Up to 5 users can Xbox Video Chat with eachother.

The camera uses an Omnivision OV530 chipset and a 512byte eeprom to store the USB device descriptor. The mainboard for the camera The OV530 chipset in the Xbox Video Camera seems to be fully backwards compatible with the older OV519 chipset used in PS2 EyeToy cameras.
The Xbox Video Chat software can be patched to use a camera with difference device IDs, but the hardware descriptors on the chipset must match the Xbox Video Camera descriptor of 1 USB device/video only.

"The package includes a camera, a 12-month subscription to Xbox Live, an Xbox Live Voice Communicator, Video Chat Disk with software needed to make it all work, and an Xbox Live Starter Kit Disk. The Xbox Video Chat provides for voice alteration and comes with 40 preinstalled background music tracks. It includes a function to turn the TV screen into a mirror temporarily, so players can groom themselves before joining a conversation."
