Linux system freeze

[antonio-petricca]

Hi, on Linux Mint 19.3 / Ubuntu 18.04 (tested with kernel 4.15 and 5.0), the first time I plugin the Tascam US 122, the USB led does not power on, so I disconnect and reconnect it, and after few seconds it lights on, but about 30/45 seconds later the system completely freezes. In that situation I must power off the PC, not event the AltSysRq reboot works, and there are not traces in the journal logs.

Could somebody help me?

Thank you so much!

Hi, we probably can't help you here so I'd suggest joining the alsa-users mailing list here at https://www.alsa-project.org/wiki/Mailing-lists and provide a bit more info about the USB card make and model and any debug from the command line (ie; dmesg as root).

I guess you have followed these steps?..

Sure, I followed the above steps, multiple times, however I got a freeze. :(

I wrote this message to the mailing list:

Hi, I am trying to use my old Tascam US-122 on Linux Mint 19.3 / Ubuntu 18.04 equipped with kernels 4.15 and 5.0.

I followed with a lot of attention the guide at https://alsa.opensrc.org/Tascam_US-122, so I fallen in the below scenario:

1. I configured the ALSA firmware.I plugged the USB card.
2. The USB led does not powered up
3. .I unplugged and plugged the card again.
4. After 30/45 seconds the US led powered on
5. .Later after a minute or two the system freezed.
6. I had to power off the PC because not even the AltSysRq reboots the system.

Could somebody help me?

Thank you again!

FWIW both the Ubuntu and Opensrc pages about the US-122 are very old and I think there is a "L" model and maybe a MKII model now that might require a different setup procedure and perhaps different firmware. Hopefully someone from the alsa-users mailing-list is using the same hardware and can set you straight. Good luck.

I own the basic model US-122 (not L or MK-II) and the guide, I checked it, is for the model I own.
