Limesdr mini isn't recognized as usb device

hi. i bought a limesdr mini about ~2 months ago and as of a week or two ago it doesn’t really uh, do anything. it does the usb data connection lost red and amber led hold, but isn’t recognized as a device at all. linux doesn’t even yell about usb descriptors or anything. is it just totally dead and garbage now? is there anything i can do to debug it?

So if you run LimeQuickTest it won’t even find the device?

If you run lsusb before and after plugging in, there is no difference at all?

nope, no yells of usb descriptors in dmesg, no signs of life in lsusb.
