lsblk -o NAME,SIZE,MODEL,VENDOR,REVISION /dev/sdX For deep inspection, use udevadm :
Here are the three most effective methods: The lsusb command lists USB buses and devices. To get chip details, use the -v (verbose) flag.
sudo dd if=/dev/sdb bs=1M count=1 2>/dev/null | strings | grep -i "alcor\|phison\|smI\|smi\|sandisk\|toshiba\|micron\|intel" Manufacturers often embed ASCII signatures (e.g., "SM3257AA" for Silicon Motion) in the firmware block. This method bypasses the controller's lies and reveals the true chip. A Dedicated Linux Tool: lsusb with a Database There is a community project that mimics ChipGenius: lsusb.py (part of the usbutils source, but enhanced by GitHub users). You can install an advanced version: chipgenius linux
udevadm info --query=all --name=/dev/sdX | grep -i "ID_MODEL\|ID_REVISION\|ID_SERIAL_SHORT" Fake drives modify their controller's response to lsusb . However, they cannot hide the internal manufacturing strings embedded in the raw NAND flash. This is the closest Linux equivalent to ChipGenius's "deep scan."
The short answer is: Native Linux Alternatives to ChipGenius Linux exposes USB device information directly through the kernel. You don't need to install a special "chip identifier" because the OS already reads this data during device enumeration. This method bypasses the controller's lies and reveals
Read the first 1MB of raw data and extract readable strings:
Identify your drive (e.g., /dev/sdb ). Be careful—this can overwrite data. However, they cannot hide the internal manufacturing strings
