 Posted: Mon Jan 29, 2024 4:39 pm Post subject: USB cassette adapter not recognized |
 |
|
I’ve just bought a cassette adapter meant to be used with Audacity,
to digitize some old recordings that are important to some of my family members.
While Linux isn’t explicitly supported by this device, it’s so simple, my thoughts were “how could it not work?”.
It’s supposed to work kind of like a USB microphone (I think). However, Audacity isn’t detecting the device,
and neither is lsusb. I’ve even tried disconnecting all other audio devices to try and isolate it, with no success.
The player works fine though, if I attach headphones to it.
This thing is supposed to be PnP, so maybe it’s a kernel issue?
Not as serious as a lot of the other stuff here, but some help would be much appreciated. |

leyvi,
Boot with it not connected.
Look at the time at the end of dmesg
Connect the device.
Post the new messages from dmesg, after the above time.
There are no drivers required from lsusb or the above test.
Do you have a make and model number for the device?
Is it supposed to be a USB host device that you connect some USB storage to and it outputs files te the USB storage?
That is, it won't connect to a PC as a PC is a host device too.

OK, here's what I've got:

|
When I bought this device, no manufacturer information was provided.
It does have "SUPER USB CASSETTE CAPTURE" written on the front of the device though, if that means anything (I don't think it does).
From what I can see here, it looks like there might actually be something going on with my kernel, since snd-usb-audio is in fact a kernel module.
I believe it's meant to be a USB slave, not a master, though I could be wrong. |

leyvi,
Google knows nothing of USB Vendor ID 8087.
If I look up BlueTrm, I get a different Vendor ID.
If its really a USB Audio Device, I would expect it to use snd-usb-audio.
Does the device mention MP3 ?

Looks like it attempts to do just that, and fails for some reason. Unfortunately I don't understand what does the rest of this line mean. Still, it is a lead.

The description on Amazon does advertise that this device can be used to convert old cassette recordings
into MP3 files, using Audacity. |

Do you have a link?

That doesn't sound promising.
That sounds even less promising, like a power source, not an interface.
What does the alleged manual say, should it work through USB?
You can try a VM with Windows 7 because the "cassette player can compatible with Windows XP, Vista and Windows 7" although the level of English seem to be compatible with the quality of the product.

Also works with laptop CD burners so it's capable of host mode operation, even if it's not host mode only.
To connect it to another host mode device, it would need to operate in USB OTG mode and not be a host.
That USB Powered is scary. It says nothing about data transfer.

I think you should return that as fast as possible. From what I read from reviews it's tricky to make it work even under Windows. It turns out there are other products with similar issues, which leads me to believe that even if you got a product without defects, you wouldn't know it because it would be impossible to set it up.
Side note: Always read 1 and 2 stars reviews first.

Holy cow. Guess Louis Rossman really was right about Amazon…
Maybe I can somehow run a 3.5 mm audio cable from the player to my
PC, and treat it as an analog microphone somehow. |

Sure way to burn your sound chip. Microphone input has different input resistance and handles signal levels lower in magnitude, compared to output to speakers or headphones. You need at least limiters, but I can't help you further as I studied that nearly 20 years ago and it wasn't the most interesting subject to me back then.
The best option you have is a player with stereo line out and some adapter with stereo line in. If you have an old casette player, chances are it has the necessary output in DIN5 standard. It's a round connector with 5 pins. They usually are 3 signal pins - one mic in and two line out and 2 ground wires - one for the mic and one for the lines out but can be 4 signal pins for stereo line in and out and a shared ground. From there you can take the necessary signals and feed them to the line in inputs of an appropriate adapter.

leyvi,
You will need an attenuator to make that work.
The cassette player output will be several volts.
The microphone input will be a few millivolts. That's 1000 times less.
Then there is the poor sound quality from a class B or even a class D audio amplifier, which you cannot fix.
Don't get me started about MP3.
That's what's left when you throw the music away.

OK, thanks for the heads up.
Guess I’ll have to find another solution. |

If you have an old cassette player, start from there. See if it has stereo line out or DIN connector. Both will do the same job. If unsure, upload a picture.
In any case, start from the player. If you have an old computer with a sound card, that's even better. I think even a motherboard with integrated audio will do the job. Connect line out to line in and voila. You'll remember good old times when you had to be there to press start, record and stop buttons manually.
p.s. don't forget to use shielded cable. Those signals are so low that even if you don't lose them you'll pick up all kinds of disturbance signals (I'm not sure if that's correctly translated in English)

logrusx,
The English technical term is 'noise' but what you wrote conveys the meaning too.
It's called the signal to noise ratio.
Adding noise is to be avoided.

Yes, that's it, thank you! It's so confusing when the general meaning of the adopted term in my native language is different. Especially hard for the things I first learned in my language.

I have this external speaker that takes headphones out
as input, and has two output ports: one marked as headphone jack,
the other marked with a little music note. Could I plug the main
input to the speaker into my cassette player (which can only output
through the 3.5 mm), and run a headphone line from the port marked
with the music note into my PC’s headphone port?
I’m assuming that this music note port is a line out port. |

Can't tell but it seems unlikely. What you assume and what it is in reality are not necessarily one and the same thing. Also line out and microphone (you meant microphone input above, didn't you?) output have different levels. It's unlikely to work even if it was line out, which I seriously doubt it is.

Hmm... I wonder if the following answer by a Gentoo Linux user to an apparently similar problem on StackExchange might shed some light on what is happening:

Do not try that at home unless you want to see if you'll have microphone or even a laptop after such an experiment.
Please do not give such advice because if your laptop survived, that doesn't mean other laptops will, and that even doesn't mean yours will survive a second time.
