When I plug it in and power it up, it does not show in fdisk -l or in Gparted or in lsblk, but it does have an entry in lsusb: Bus 001 Device 000: ID 0dc4:0201 Macpower Peripherals, Ltd I have one particular older drive that has been sitting on my shelf for about 10 years (an "EZ Quest" from about 2005), but it worked the last time I used it, so I doubt the drive has failed. If those values for your hardware don't match the values listed above, OpenOCD won't recognize the Flyswatter.I'm running Mint/Mate 17.3 and normally external drives "just work" when you plug them in. Pay careful attention to the values following idVendor, idProduct, iProduct, and iSerial. IdProduct 0圆010 FT2232C Dual USB-UART/FIFO IC For the original Flyswatter, you should see something like this: idVendor 0x0403 Future Technology Devices International, Ltd Scroll up through the information about your hardware. Now get more information about the device by typing: sudo lsusb -v -s :įor example, if you had seen the output listed above, you would type: sudo lsusb -v -s 002:006 The bus number and device number will likely be different, but take note of them. For the Flyswatter you should see something like this: Bus 002 Device 006: ID 0403:6010 Future Technology Devices International, Ltd FT2232C Dual USB-UART/FIFO IC Look for the hardware you want to use with OpenOCD. This will display a list of all USB devices connected to your computer. To use lsusb, open a terminal window and type: sudo lsusb The lsusb command provided in Ubuntu Linux provides information about USB devices connected to your computer.
