Hi all,

I have a thinkpad x240That I am trying to use with my Behringer UMC404 USB soundcard. The problem is that it is not recognized a boot, and as soon as unplug/replug it in, it appears in the sound properties and disappears, doing so between 10 and 20+ times, each time with a light "pop" from my speakers. dmesg show that it is disconnected in a loop and increments the device number, as well as a bunch of "usb 1-3.3: 1:1: usb_set_interface failed (-71)", as well as a few "xhci_hcd 0000:00:14.0: URB transfer length is wrong, xHC issue? req. len = 0, act. len = 4294967288 " every onece i a while. When playing sound it just pauses the sound output if I select my USB sound card. I have tried disabling USB powersaving to no avail.

Does anyone know a solution to this problem ?

Thanks in advance !
