Unregognized usb device after hibernation

diegomagikal · 08-01-2020, 05:50 PM

Hello all! This is my first post. Thanks in advance for any help!

I bought a Focusrite Scarlet 2i2 (interface usb audio) and it worked very well in my Ubuntu 20.04. The USB connection has been recognized as new device and all worked fine (audio input and audio output).
But since my computer hibernated for a few minutes and woke up, the usb connection is unrecognized (I can't see the Scarlet as an usb device). The usb port still can power the interface, but the audio output doesn't works anymore (although the audio input is ok).
I tested it on another 2 windows pcs and the same occurs.

My hypothesis is that the partition table has been corrupted. But I don't know what to do (I have no experience with that).

With lsusb command, I can see the Focusrite Scarleth:

Code:

With lsblk command, I can't see Scarleth data:

By running fdisk -l, I got the red text "Partition 2 does not start at a physical sector boundary" and "Partition table entries are not in disk order". But what is the disk it refers to?

With dmesg command, after disconnect and reconnect the usb cable I get the following code:

Code:

I don't know how to interpret this information... Can you help?

Thanks

The partition table and USB are not interconnected the way you seem to assume AFAIK. Probably you should better concentrate on USB -- which I don't know well. For other readers: Is there a demon or some background service which has to be running using USB-devices? If so, the OP could check on his machine...

Thanks. Just in case, I already reset the usb port with usb-reset tool, but with no effect. The question is that I get the same error in anothers computers, including windows machines.

I thought about partition table because when I plugged the device before, a partition with some files a appeared (like https://pasteboard.co/Jkx4cJT.png). But now, when I plug the device nothing happens.

Sorry, it says "Image not found".

Partition tables errors simply make no sense: They are indices of hard discs layouts. USB is dynamic, i.e. plug in and the device is known. That's why I asked for demons or background services (which I don't know of but might get killed by hibernation).

Ahh, now I see what you mean. What happens is that with end of hibernation your system "perceives" the device as an USB-hard disc. No idea how to correct that. Google?

It's not entirely clear from your post, but I assume this device was working in both windows and Ubuntu before. Then after hibernation in Ubuntu, the device no longer works in either. Please confirm. Also, by hibernation, did you suspend to ram or disk?

Your output demonstrates that two storage devices have been detected, a 500GB Toshiba hard drive and a 500 GB Sandisk SSD where your operating system is installed. The red error message from fdisk is a common one and can be ignored; it is of no significance. To illustrate here's the same error message in my fdisk output:

Code:

# fdisk -l

Partition 1 does not start on physical sector boundary.

Your dmesg output shows that on reconnecting the device, your system is loading the ehci-pci driver for the device which is the driver for usb storage devices. I am curious as to whether lsblk then shows another storage device, sdc.

I assume this is the device we're talking about:
https://www.amazon.com/Focusrite-Sca.../dp/B07QR73T66

This is a device for recording audio and since it is not clear whether the device has its own internal storage , I'm guessing that the device is designed to place its recordings on the attached computers internal hard drive. If it does have internal storage, that would explain the loading of the ehci-pci driver and F: drive letter in windows; it's for accessing the devices internal storage. Also, on the Amazon website reviews, there's some question as to whether the device is supported by Windows 10.

If you are connecting via a USB3 port, I would suggest trying the device on a USB2 port if one is available. The specs for the device show it is designed for USB2. USB3 is supposed to be backward compatible but I've had issues with some USB devices acting flakey on USB3 but working fine on USB2.

Other than that, I would contact the manufacturer and try to get a replacement under their 3 year warranty.
