If the device is detected but the filesystem is corrupt, reformatting may be sufficient:
The PID 1234 is often found in devices that support not covered by standard USB storage specifications. For example, Alcor’s proprietary protocol can switch the device from removable disk mode to a CD-ROM (device firmware upgrade) mode, which is useful for deploying autorun content or firmware patches. This flexibility, however, has been exploited in "BadUSB" attacks, where a maliciously reprogrammed Alcor controller can emulate a keyboard or network card. While not inherently insecure, the availability of public firmware flashing tools for this VID/PID makes it a double-edged sword: legitimate for OEMs, dangerous if the device falls into untrusted hands. usb device id vid 058f pid 1234 full

If you are comfortable sharing the (e.g., AU6986, SC708) or a screenshot of the ChipGenius output , I can suggest specific Alcor MP Tool versions to help repair it.
The USB device ID is almost always an Alcor Micro USB 2.0 Hub or a basic multi-card reader. In 99% of cases, you do not need to download any external driver. Your operating system’s native USB stack will handle it.
You will typically experience this issue in a few distinct ways:
