There are official drivers for Windows and Mac. and going back to Windows is a big turn off for me.ĮDIT1: I forgot to say this is a device not officially supported by Ubuntu or Tascam, which has discontinued the product. I don't want to give up, because as I said it worked before. I'm googling everything related to this problem with no success. plugged/unplugged in every USB hub, all of them work fine with other devices like optical mouse. I've tried several things like tosuspend=-1, iommu=soft, the "unplug everything for 3 min" trick. usb 3-1: 30:0: cannot get min/max values for control 5 usb 3-1: 30:0: cannot get min/max values for control 4 usb 3-1: 30:0: cannot get min/max values for control 3 usb 3-1: 30:0: cannot get min/max values for control 2 usb 3-1: 30:0: cannot get min/max values for control 1 usb 3-1: cannot get ctl value: req = 0x83, wValue = usb 3-1: New USB device strings: Mfr=12, Product=13, usb 3-1: New USB device found, idVendor=0644, idProduct=802a usb 3-1: config 1 interface 4 altsetting 0 bulk endpoint Strange thing is, when I tried with a Live version of Ubuntu from a flash drive, I get a different kind of error: usb 3-1: new high-speed USB device number 3 using ehci-pci usb 1-1-port2: unable to enumerate USB device usb 1-1.2: new full-speed USB device number 12 using ehci-pci usb 1-1.2: device descriptor read/64, error -32 usb 1-1.2: new full-speed USB device number 11 using ehci-pci usb 1-1.2: device not accepting address 10, error -32 I'm getting this error in dmesg: usb 1-1.2: new full-speed USB device number 10 using ehci-pci


Tried again in my wife's laptop with Windows - working fine. The same device was running Ok on Windows 10 a few days ago. I just dumped Windows out of my system, tried first Ubuntu Studio 19.10 and now Ubuntu 18.04, with no success.

I've done it before years ago, same hardware, can't remember what Ubuntu Studio version. I'm trying to make an audio interface - Tascam US-800 - to work. I'm on Ubuntu 18.04 on a Dell 3442 laptop.
