Change CID of SD Card on Ubuntu

When using a microSD card in an SD card slot, it's often necessary to spoof the Card Identification Number (CID) of the card. This can be especially useful when you need to use a user-defined card ID for a specific application or purpose. One way to achieve this is by using the SpoofCID adapter, which allows you to swap the CID of your microSD card and make it appear as a regular SD card.

Fortunately, using the SpoofCID adapter with Ubuntu is relatively straightforward. The adapter is compatible with both UHS (Ultra High Speed) hosts and cards, making it suitable for most modern devices. However, there are some important considerations to keep in mind when using this adapter.

Firstly, if your device supports UHS but your SD card does not, you won't encounter any issues. On the other hand, if both your device and SD card support UHS, you may experience problems due to 1.8V signaling, which is a limitation of UHS technology. Fortunately, most commercial applications of SD cards use SDIO (which is supported), so this issue should not be a major concern.

To use the SpoofCID adapter with Ubuntu, simply insert your microSD card into the adapter and then connect it to your device's SD card slot. The adapter will automatically swap the CID of your card with the user-defined ID you've specified. You can then access your card as if it were a regular SD card.

It's worth noting that using the SpoofCID adapter does not void any warranties or guarantees associated with your device or SD card. Additionally, the authors and copyright holders of the adapter disclaim all liability for any claims, damages, or other liabilities arising from the use of the product.

In summary, the SpoofCID adapter provides a convenient way to change the CID of your microSD card on Ubuntu-based devices. By using this adapter, you can easily swap the CID of your card and make it appear as a regular SD card with a user-defined ID. While there may be some limitations to consider when using UHS technology, the SpoofCID adapter is generally compatible with most modern devices and should not pose any major issues.
