USB

Further infos about USB - Universal Serial Bus.

USB IDs

• For Open-Source Projects:
  • USB IDs from pid.codes
  • USB IDs + MAC Addresses from Openmoko, List on GitHub
• Microchip USB IDs for Microchip Products
• NXP USB IDs for NXP Products
• Buy USB PID from MCS Electronics
• List of obsolete USB VIDs
• USB VID 0x6666 is a Prototyping Vendor ID

USB CDC/VCP (COM-Port)

Drivers

• FTDI FT23x VCP Drivers
• SiLabs CP210x VCP Drivers
• Holtek VCP Drivers

Static COM-Port Number under Windows

To disable the USB serial number recognition on Windows (same boards will have the same COM-Port number) the following registery entry has to be created:

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\UsbFlags]

GlobalDisableSerNumGen Type=REG_BINARY Data=01
    0 disable all USB serials
    1 enables USB serials

IgnoreHWSerNum11118888 Type=REG_BINARY Data=01
    1111 = VID (Vendor ID)
    8888 = PID (Product ID)

Slow speeds on FTDI devices (FT232, FT245…)

The FTDI driver sets a 16ms latency delay on Windows systems as default (further infos). You can decrease this setting to speed up the communication. It can be found in the device manager in the settings of the respective COM-Port: Advanced... -> BM Options -> Latency Timer
