This will lead to bad user experience and, in a worst-case scenario, can damage the device.
USB VID DRIVER UPDATE
If two different products share the same VID/PID tuple then an operating system will potentially load the wrong device driver, and another product's applications and utilities will possibly try to communicate with the device, perform a firmware update etc. So a unique VID/PID tuple is essential for the operating system to locate the correct device driver. On Windows, any vendor-specific USB device driver will be loaded based on VID/PID identification. typically rely on the VID/PID tuple to identify the device they have been designed for.
Software applications such as configuration tools, firmware upgrade utilities, etc. last volume set for a given device instance). Operating systems (Windows, macOS, Linux) use the VID/PID tuple to locate the matching device driver, and to store device-specific configuration information (e.g. A USB device reports these numbers through its device descriptor in the fields idVendor and idProduct. Each number ranges from zero to 65536 (0x0000 to 0xFFFF). Įvery shipping USB product is uniquely identified by a tuple of two 16-bit integer numbers: vendor ID (VID) and product ID (PID).
USB VID DRIVER DRIVERS
Windows 10 is not affected as drivers are to be attestation signed.Ĭonsequently, any kernel-mode driver released for Windows 7/8/8.1 after Jrequires WHQL signing (aka HLK/HCK). This affects Windows 7 and 8/8.1 as these systems require a cross-signed driver. As of JMicrosoft discontinuous cross signing. Signing kernel-mode drivers with a vendor certificate issued by one of the commercial CAs requires a cross certificate issued by Microsoft. What's the purpose of the static COM port feature in the TL-USBCOM driver? Why I can no longer sign Windows kernel-mode drivers with a vendor certificate? Why does Windows 7 not accept my signed driver?Ĭan Thesycon’s USB network driver be used as a replacement for Microsoft's RNDIS driver? What is the difference between code signing and Windows Logo Signing (WHQL)? Why does Thesycon not allow to use the licensed driver with USB VID/PID identifiers from a silicon manufacturer's evaluation board? Why should I use unique VID/PID identifiers for a Linux Gadget based product? Why do I have to customize a device driver provided by Thesycon?
