Usb SSD disk not detected on Ubuntu 18.04

dr_berta · 11-18-2019, 07:36 AM

Hi,
I took a 60GB ssd disk to be used with a raspberry pi, instead of the microSD, via the SupTronics X820 board.
I mounted the disk on the board and connected it to my system with Ubuntu 18.04 to be able to install the raspbian.
Unfortunately the disc is not recognized.

Giving the command

Code:

cat /proc/partitions

I don't see any new disk neither using gparted o fdisk.

Giving the command

Code:

lsusb

this is the result:

Code:

 Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 009 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

The empty row is the one of the board X820 connected to the disk.

The command

Code:

dmesg | grep usb

gives me this result:

Code:

[   25.344114] usb 2-4: new high-speed USB device number 4 using ehci-pci
[   25.501974] usb 2-4: New USB device found, idVendor=0820, idProduct=0003

The x820 board usb ports are usb3.0 while my system has a usb2.0 port
Do you have any suggestions on how to show them the disc?

Thanks
Claudio

I think you have answered your own question, if I understand your setup correctly.

Your computer/system only has USB 2.0 ports, whilst the RasPi and X820 motherboard both use USB 3.0.
The supplied blue cable is USB 3.0 (see attached jpg).

I think you need to buy a USB 3.0 (2 or 4 port) PCIe expansion card similar to this:

As far as signalling, USB 3.0 is backwards compatible (other than being slower), so power would be the only reason that wouldn't work in a 2.0 slot. Is that a standalone power plug on the board? If so, do you have a power adapter for it? Plugging it in so it was able to get the power it needs to function should allow it to work in a 2.0 slot. Otherwise, agreed with beachboy2, you probably will need to get a USB3.0 add-in card in order to deliver sufficient power for the board to work.

Claudio,

I have just discovered this in the X820 FAQs:

Quote:

Question 3:What to do if the X820 board could not detect the HDD or SSD?

Answer:
(1) At first, please use the high quality power supply adapter, the hard disk will not be recognized if you use the low quality power supply, as the current of this power supply is not enough.

(2) Please run 'lsusb' command under linux terminal, and save the screenshot of the result, then send it to our email: sp@geekworm.com, then we will figure out your problem together.
