# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.
# Line up the first '|' above the ':' following the base package name, and
# the '|' on the right side marks the last column you can put a character in.
# You must make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':' except on otherwise blank lines.

USB Vendor and Device ID List for rtl8812bu and rtl8822bu chipset based USB WiFi Adapters

To determine your Device ID:

$ lsusb

Example output:

Bus 003 Device 011: ID 0bda:b812 Realtek Semiconductor Corp.

ID VendorID:DeviceID = 0bda:b812

We can search the list of driver supported IDs shown below.

Realtek default IDs (3)

ID 0BDA:B812 - Default ID for USB Single-function, WiFi only
ID 0BDA:B81A - Default ID
ID 0BDA:B82C - Default ID for USB multi-function (such as WiFi plus bluetooth)

Seller specific IDs (29)

ID 04CA:8602  /* LiteOn */
ID 056E:4011  /* Elecom */
ID 0846:9055  /* Netgear A6150 */

If your adapter matches one of the default or seller specific
IDs then this is the driver to use.

Info: location of file that contains the IDs: /os_dep/linux/usb_intf.c

If you are sure that your adapter contains either a rtl8812bu
or rtl8822bu chipset and the ID is not shown above, please provide
the follow information so that I can include your adapter in the
driver source code so that the driver will work with your adapter:

1. VendorID:DeviceID
2. Link to device on internet
