If this matches, you have confirmed the device's identity. In the event the driver fails to load automatically, you can manually update it by selecting "Browse my computer for drivers" and pointing it to the standard Windows driver store, which will contain the necessary INF files for mass storage devices.
The USB\VID_14CD&PID_1212 identifier points to a ubiquitous class of budget-friendly, low-performance USB storage devices, typically microSD card readers built around a chipset from Moai Electronics. While they work seamlessly with the generic drivers in most modern operating systems, their USB 2.0 bottleneck and occasional compatibility issues with larger SD cards can be frustrating. The most common problems—constant reconnection, 0-byte capacity, and formatting failures—are often resolved by switching USB ports, manually reinstalling the generic driver on Windows, or using specialized formatting tools, but some may be inherent hardware limitations of this design.
The device appears in Windows Disk Management or diskpart , but its capacity reads as 0 Bytes , and it is labeled as . This indicates that the Super Top controller chip is powered on and communicating with the computer, but it cannot establish a connection to the internal flash memory chip or the inserted microSD card. 2. Device Disconnect Loops
This specific combination of Vendor ID (VID 14CD) and Product ID (PID 1212) commonly belongs to ultra-budget external USB 2.0 adapters, such as the widely distributed . Because these generic devices are sold worldwide under hundreds of unbranded or white-label logos, identifying them by their alphanumeric hardware ID is the only definitive way to troubleshoot connectivity, driver conflicts, or storage corruption. Decoding the Hardware ID: VID 14CD and PID 1212 Usb Device Id Vid 14cd Pid 1212-
: The device uses the standard usb-storage driver. This driver should work in principle, but this specific device is known to have significant compatibility issues, which are detailed in the next section.
Users tracking down this hardware ID typically do so because the device has encountered an error. Because MOAI/Super Top chips are widely deployed in white-label (unbranded) card readers, they are highly prone to a few specific software and hardware bottlenecks. 1. The "No Media" or "Write-Protected" Error
Another common problem is that the system detects the reader via lsusb , but does not create a device node (like /dev/sdb ), making it impossible to access the card. A workaround suggested by users is to add a kernel "quirk" for the device. This involves editing the kernel boot parameters to include usb-storage.quirks=14cd:1212:u and then rebooting. This forces the kernel to use a specific, more compatible driver for that device. If this matches, you have confirmed the device's identity
This vendor ID is assigned to Super Top or STEC (often affiliated with ASUS and other OEM mass storage solutions).
), which can occasionally cause conflicts if multiple identical units are plugged into the same system. unix.stackexchange.com 3. Usage & Performance Based on community data from NirSoft's USB Speed Tests
However, the actual chips inside these devices are often sourced from , a Taiwanese company, making them OEM (Original Equipment Manufacturer) products —devices created by one company to be branded and sold by another. The most common product associated with this ID is the Super Top SY-T18 microSD card reader . While they work seamlessly with the generic drivers
: Users typically see write speeds between 7 MB/s and 15 MB/s , depending on the quality of the microSD card inserted. Troubleshooting: "USB Device Not Recognized"
Users typically search for this ID when they experience:
