Based on the hardware IDs you provided (VID 0c45 PID 627b), this refers to a Microdia Sonix USB 2.0 Camera (often integrated into laptops or sold as generic webcams).
The term "Patched" in this context almost always refers to a specific community workaround for older Sonix webcams that lost official driver support or had bugs on newer versions of Windows (specifically Windows 10 and 11).
Here is an interesting guide on what this "patched" status means, why you likely need it, and how to set it up.
The "patched" status for VID 0c45 PID 627b is a badge of honor for this hardware—it represents a user-modified solution to keep legacy hardware alive on modern operating systems. If you are trying to use this today, the "Have Disk" installation method combined with Media Feature Pack is your best route.
The hardware ID USB VID 0C45 PID 627B identifies a webcam manufactured by Microdia. While the specific "627B" product ID is a variant of the common Sonix (SN9C) controller series, it is notoriously difficult to support on modern operating systems because it often lacks native UVC (USB Video Class) compliance.
The term "patched" in this context typically refers to one of three scenarios: a Linux kernel driver patch, a Windows INF driver modification, or a firmware override. 1. Linux Kernel and the Microdia Project
Historically, many Microdia cameras (like those with PID 6270 or 627B) were not recognized by standard Linux drivers. Users often had to apply a "patched" driver from the Microdia project on repo.or.cz to make them functional.
The Solution: Developers wrote a custom kernel module (microdia.ko) that translated the proprietary communication protocol of the Sonix SN9C chipsets into something the Linux video capture interface could understand.
Implementation: This required cloning the driver source, compiling it against the current kernel, and manually loading it using modprobe. 2. Windows Driver Patching (INF Modification)
On Windows, these cameras often fail to work with the default "USB Video Device" driver, resulting in errors like Code 45 (Device not connected) or NoCamerasAttached.
The "Patch": A common workaround involves downloading a legacy driver (often for the Sonix SN9C201 usb vid 0c45 pid 627b rev 0100 patched
) and "patching" the .inf setup file to include the specific VID_0C45&PID_627B hardware ID.
Outcome: This forces Windows to associate the non-standard hardware with a compatible (though older) driver, sometimes bypassing the "camera not found" errors in apps like Skype or Zoom. 3. Firmware and "Fake" Capacity Patches
In some specialized cases, the term "patched" is used when a device's revision number (Rev 0100) has been altered at the firmware level.
Fake Storage: While common in USB flash drives to spoof storage capacity, in webcams, firmware patching is usually limited to resolving specific synchronization issues or "flipping" the image if the sensor was mounted upside down by the manufacturer. Camera Firmware Upgrade Tutorial
The term "patched" in this context usually refers to a specific modification of the device driver or firmware. Here is why this is significant:
The USB VID 0C45 PID 627B REV 0100 is a widely sold, budget-friendly imaging device. While functional on modern Linux, it is notoriously difficult on macOS and requires specific "patched" drivers on Windows to function correctly. If you are looking for the "patched" file, you are likely looking for the modified driver that enables video decoding for the Sonix chipset inside this device.
The hardware identifier USB VID 0C45 PID 627B REV 0100 refers to a specific generation of webcams manufactured by Microdia (using Sonix controllers). These devices are frequently integrated into older laptops or sold as generic external USB 2.0 cameras.
The term "patched" in this context typically refers to the use of modified or legacy drivers to make these aging hardware components compatible with modern operating systems like Windows 10/11 or modern Linux kernels. Understanding the Hardware: Microdia/Sonix
VID (Vendor ID) 0C45: Registered to Microdia, a major OEM for webcam modules.
PID (Product ID) 627B: Identifies the specific controller chip, usually from the Sonix SN9C series.
REV (Revision) 0100: Indicates the first firmware version of this specific hardware iteration. Common Issues and Why "Patches" are Needed
Many users encounter a "No Cameras Attached" error (code 0xA00F4244) because the original manufacturers stopped providing official updates over a decade ago.
Driver Signature Requirements: Modern Windows versions require digitally signed drivers. Older Microdia drivers often lack these, requiring a "patched" installer or a manual override of driver signature enforcement.
UVC Compliance: While newer webcams use the universal "USB Video Class" (UVC) driver, older Sonix-based units often require a proprietary bridge driver to communicate with the OS.
App Compatibility: Even if the driver installs, modern apps like Zoom or the Windows Camera app may not recognize the legacy stream format without a patch to the registry or the driver's .inf file. How to Resolve Connection Errors
If your device is showing up as "Generic USB Hub" or an "Unknown Device" in Device Manager, follow these steps: 1. Windows: The "Digital Viewer" Patch
Users often find success by forcing the device to use the Sonix SN9C201 driver.

I downloaded the kernel source (or cloned the gspca staging driver) and modified drivers/media/usb/gspca/sn9c20x.c.
Key insight: For rev 0100, the driver sends register 0x01 with value 0x08 (power down) but never sends 0x00 (wake up) before streaming.
Here is the patch I applied:
