In order to compile a hardware device please follow these instructions:

Write the vendor name as it is printed on the device itself (or on the device box). If it is integrated (for example a wifi card in a notebook), write the vendor as written in the lspci command.

It the vendor name printed on the device itsel is different from the one indicated on the lspci command, choose the first one (the one printed on the device)

If the vendor is not in the list, please open an issue requesting the insertion of the vendor

If you have tested the device with more than one distribution please specify the oldest kernel version (among the ones of those distributions)

please do not forget to insert the vendorid:productid code since it is used to find a device in the search page.

Also, the system checks that a device with the same code is not present in the database. This is useful to avoid hardware duplication

(Thanks Michał Masłowski and Julius22)

Open a terminal and type the following command:

sudo lspci -nnk

You should obtain a list of hardware similar to the one written below

03:00.0 Network controller [0280]: Broadcom Corporation BCM4311 802.11b/g WLAN [ 14e4:4311 ] (rev 02)
	Kernel driver in use: b43-pci-bridge
	Kernel modules: ssb
	05:00.0 VGA compatible controller [0300]: nVidia Corporation G86 [GeForce 8400M GS] [ 10de:0427 ] (rev a1)
	Kernel modules: nouveau, nvidiafb

The strings in bold and placed inside the square brackets (in the above list) are the code you are looking for. The first set of digits (before the colon) are the VendorID, the second set of digits are the ProductID. In the above example: the VendorID:ProductID code of the wifi card (note the strings "Network controller" and "WLAN") is 14e4:4311 while the VendorID:ProductID code of the video card (note the string "VGA") is 10de:0427

Open a terminal and type the following command:

sudo lsusb

You should obtain a list of hardware similar to the one written below

Bus 001 Device 002: ID 0846:4260 NetGear, Inc. WG111v3 54 Mbps Wireless [realtek RTL8187B]
	Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
	Bus 002 Device 003: ID 08ff:2580 AuthenTec, Inc. AES2501 Fingerprint Sensor

The strings in bold (in the above list) are the code you are looking for. The first set of digits (before the colon) are the VendorID, the second set of digits are the ProductID. In the above example: the VendorID:ProductID code of the external USB wifi card (note the strings "Wireless") is 0846:4260
