Before you plug it in, open a command line and run: dmesg Open another command line window, plug it in, and run dmesg in the second window. Now you can compare the messages at the end of each dump against each other. If it recognised the hardware, you should get some information about it. If not, a simple first test is to try another USB lead. You can have broken data lines, and still have functioning power lines, within the cable, allowing it to charge. By way of example, when I plug in a webcam, it shows all this gubbins: [3887829.895943] usb 1-12: new high-speed USB device number 51 using xhci_hcd [3887830.123901] usb 1-12: New USB device found, idVendor=0c45, idProduct=6366, bcdDevice= 1.00 [3887830.123928] usb 1-12: New USB device strings: Mfr=2, Product=1, SerialNumber=3 [3887830.123936] usb 1-12: Product: CM200 [3887830.123943] usb 1-12: Manufacturer: Sonix Technology Co., Ltd.
