I'm trying to connect my external hard drive to my Raspberry Pi 2B, but I am not able to get it to show up. I am running the latest Raspbian, and I have updated my software. Running lsblk --fs, I only see the SD card.

NAME        FSTYPE LABEL  UUID                                 FSAVAIL FSUSE% MOUNTPOINT
mmcblk0
├─mmcblk0p1 vfat   boot   4467-8C16                             197.6M    22% /boot
└─mmcblk0p2 ext4   rootfs 66f68227-b1ae-4493-9ef5-e593576a6e81    5.7G    55% /

I have been getting the following error in dmesg

[  890.258022] usb 1-1.2.1: new full-speed USB device number 11 using dwc_otg

I initially thought it was a power issue from the Raspberry Pi, so I connected it to an external powered USB hub but I am still seeing the same issue. I have confirmed that the drive works through the hub on my PC.

I also tried setting max_usb_current=1 in my /boot/config.txt and rebooting, but no luck with that either. I am using this hard drive enclosure and this powered USB hub.

Does anyone have an idea how to resolve this?

  • what hard drive do you have in the enclosure? Commented Jan 4, 2021 at 6:47
  • what's the output of lsusb Commented Jan 4, 2021 at 7:00
  • It seems that many things from Amazon have issues these days. There have been reports that Amazon no longer exercises any quality control over their vendors. I would send it back to them for a refund.

  • @JaromandaX, this is the lsusb output: ``` pi@raspberrypi:~ $ lsusb Bus 001 Device 010: ID 05e3:0610 Genesys Logic, Inc. 4-port hub Bus 001 Device 003: ID 0424:ec00 Standard Microsystems Corp. SMSC9512/9514 Fast Ethernet Adapter Bus 001 Device 002: ID 0424:9514 Standard Microsystems Corp. SMC9514 Hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub ``` The hub shows up but the drive doesn't. The hard drive is just a 1TB 2.5" drive from Toshiba

    I can't read that ... perhaps you should put that in the question to make it readable Commented Jan 5, 2021 at 2:11
