No interrupt endpoints are common unless the device emulates a CDC ACM class.
HKLM\SYSTEM\CurrentControlSet\Enum\USB\VID_FFFF&PID_1201
Usually, —not with standard software like Recuva or EaseUS. Because the OS cannot address the device correctly, file recovery software cannot scan the sectors. usb device id vid ffff pid 1201
The specific PID 0x1201 further narrows the identification.
This is the most promising solution but is complex and risky. No interrupt endpoints are common unless the device
Run the process. This will overwrite the damaged controller firmware, scan for bad blocks, and reconstruct a healthy file partition.
Try a different USB port or a different computer to rule out power-supply issues. The specific PID 0x1201 further narrows the identification
USB Device ID: VID = FFFF PID = 1201 Device Revision: 0000 Manufacturer: NAND Product Model: USB2DISK Product Revision: 0.00 Controller Vendor: FirstChip Controller Part-Number: FC1178BC
If the internal voltage regulator on the USB device's circuit board fails, the chip may still power on enough to send a signal, but not enough to read its proper internal memory. The default fallback signal is often FFFF:1201 .
