Draws a standard 100mA to 200mA max current, making it highly compatible across low-power ports. Common System Failure Symptoms
There are three primary reasons:
These devices are not built for speed. A detailed review of a USB\VID_14CD&PID_1212&REV_0100 card reader confirmed it's a USB 2.0 device, which realistically caps performance far below the theoretical 480 Mbps of the standard. In sequential read/write tests, this adapter achieves around 20 MB/s for reading and about 14 MB/s for writing when used with a modern card. For comparison, a USB 3.0 reader can easily exceed 80 MB/s. Its speed is adequate for transferring a few photos or music files, but it becomes a bottleneck for large video files or SD cards with capacities over 32GB (SDXC).
According to technical logs, here is what is happening under the hood of a typical VID 14CD PID 1212 device: : USB 2.0 (High Speed). Power Consumption : Typically draws between 100mA and 250mA .

Because this device belongs to the , it generally does not require proprietary drivers.
Here is a quick reference for the device's key specifications.
Ironically, the VID 14CD PID 1212 controller is robust and cheap, which is why it appears in hundreds of "off-brand" external enclosures. The problem is rarely the hardware. The problem is .
The PID 1212 reader is an older USB 2.0 device. Its components may fail over time, rendering it irreparable. Conclusion Draws a standard 100mA to 200mA max current,
If you’ve tried all of the above and:
Users typically search for this ID when they experience:
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.
Fix 3: Power Management SettingsWindows sometimes turns off USB hubs to save energy, causing the hub to "disappear."Right-click the device in Device Manager.Go to Properties > Power Management.Uncheck "Allow the computer to turn off this device to save power." Technical Specifications of VID 14cd PID 1212 In sequential read/write tests, this adapter achieves around
If the generic driver fails, you can manually create or download an INF file:
Points directly to Super Top (sometimes identified in database logs as generic Mass Storage or associated with AppoTech/Buildwin controllers in low-tier manufacturing runs).
| Symptom | Likely Fix | |---------|-------------| | Not detected at all | Bad cable, USB port, or power. Try Y-cable / powered hub. | | Yellow exclamation mark | Uninstall driver → reconnect. | | "Not intended for platform" | Manually force "Standard CD-ROM Drive". | | Code 31 or 39 | Delete UpperFilters/LowerFilters in registry. | | Reads CDs but not DVDs | Dirty lens or region lock. Clean lens with cotton swab + isopropyl alcohol. | | Works then disappears | Windows power management → Disable USB selective suspend. |
Connecting a USB mass storage device to an Android phone or tablet is not as straightforward as on a desktop OS. Most Android devices do not natively include drivers for external USB storage and rely on the OS's kernel for support. However, if you are an Android developer using , the VID/PID becomes extremely relevant. You may need to add the vendor ID (14CD) to the adb_usb.ini file on your computer to allow ADB to recognize the device for debugging purposes.
The flash memory inside the device is damaged, making the PID unrecognizable.
